If you can't solve this there is no way you will ever make it in crypto

by inspection is used in mathematics when you solve a problem by looking at it

You typed in the problem

dunno lol

(4+3*0)(4+3*14)=49

easy??

Never mind i'm retarded.

This is a nontrivial polynomial equation of degree, so there exist only 2 solutions. He has found both of them, hence he is done with finding all of them.

Inspect element in chrome, you could HTML the fractions

(4+3*1)(4+3*1)

literally high school math in America

>implying high schoolers learn anything between black classmates getting arrested in class and mexicans dealing drugs on the toilet while whites go on a rampage in the cafeteria

x = 1

What the fuck? How would you not be able to solve this? This took 2 seconds of mental math.

x=1

There is two solutions dolt. -11/3 is also a solution.

It makes me sad that people think Jow Forums users are smart and literally can’t solve the most basic of algebra equations

Why is there no multiplication sign between the 2 arguments? Is this normal in burgerland?

Trick question... the answer is already listed dumbasses. It's 49

uh.... I have bad news for you user

>foil
>quadratic equation

Except you don't need any of those to solve this question.

For the brainlets, first FOIL (first, outer, inner, last) which gives you:

16+12x+12x+9x^2=49

Put in quadratic form:

9x^2+24x-33=0

If you don’t know the quadratic equation, you should not have passed 4th/5th grade math.

This. You should be able to just look at this and see know the answer is '1' as 7*7=49

Not sure how one would easily come up with -11/3 as a solution without using the quadratic equation, but also haven’t solved any such algebra equations in a long time. How would you solve?

This. But -7*-7 is also 49 so that means 3*x has to be -11 which means x can also be -11/3.

>math genius
>fails at copy&paste

So how do you “just look at it” and see that -11/3 also satisfies the equation...?

If anyone wants to know how to actually work it out manually:

>4*4 = 16
>4*3x=12x
>3x*4=12x
>3x*3x=9x^2
>9x^2+24x+16=49
>9x^2+24x-33=0
>3(3x^2+8x-11)=0
>3x^2-3x+11x-11=0
>3x(x-1)+11(x-1)=0
>(3x+11)(x-1)

>3x+11=0
>3x=-11
>x=-11/3

x-1=0
x=1

Result: x = 1, x = -11/3

Haha, yea, that works too...good point

dumbass gets half-credit

When doing the square root of 49, the result is both plus and minus 7.

>Has math minor
>Still has to google quadratic formula

I'm not going to make it - also college is a fucking joke

see

I hope this is a larp thread

Clearly the values in () must both be 7 or negative 7. x=1 works for seven and to get -7 you need to add 4 and -11 but you multiply x by three so that's -11/3

negative numbers don't actually exist.

great job wasting time using the quadratic formula when it wasn't necessary.

I think I stopped keeping an easy pace with math class around 6th grade. I can barely do the shit in my head.

x=1
7x7= 49
have 6000k LINKS, will l make it?

what's this retarded shit?

solved the equation in my head in 5 seconds

x=1
x=-11/3

at first glance you will notice both parentheses are the same so its simply ()^2. the other side is 7^2 or -7^2
4*3x = 7 and 4*3x= -7 is basic math then

x=1 could certainly work. But other solutions? impossible to know

The ONLY right way if you did actual algebra

(4+3x)(4+3x) = 49
(4+3x)^2 = 49
4+3x = 7
3x = 3
x = 1

x=1

> Interesting, since if you fill in x = -11/3 in the original formula, it gives a solution.

Hmmmmmmmmmmm
Why dont these threads ever get a decent fucking math problem. This is all kiddy shit.

It is squared and polynomial equations have two solutions, one negative, the other is positive.

If you couldn't figure this out intuitively you're fucking never going to make it

I hope you're trying to troll because you unironically got it wrong dude

>solve for x
(4 + 3x)(4 + 3x) = 49
>also written as
(4 + 3x)^2 = 49

>you start by multiplying each pair of terms
3x * 3x = 9x^2
4 * 3x = 12x
3x * 4 = 12x
4 * 4 = 16

9x^2 + 12x + 12x + 16 = 49

However, I don't remember how to solve X from that point

Thank you

retard.

(4 +3x) are both the same.
so
>a * a = 49;
>sqrt(49) = 7;
>4 + 3x = 7;
>7-4 = 3;
>3x = 3;
>x=1;

>sqrt(49) = 7
the worst part is that nobody in this thread managed to figure out sqrt has two results, not one.

see

I hope you were joking

>sqrt can be more than one number
>pfft hblfff plftttt

Attached: Screen Shot 2018-07-14 at 22.44.36.png (454x450, 82K)

or you could take the square root of both sides:

(4 + 3x)^2 = 49
... take square root, remembering the negative solution ...
(4 + 3x) = 7 or (4 + 3x) = -7
... solve via normal means ...
x = 1 or x = -11/3

is this the power of the american superstate?

he's being pedantic, but he's technically right
the square root of 49 can only be 7
but you're right that if x^2 = 49, x can be 7 or -7

i'll take that as a yes

Kek

(4+3x)(4+3x)=49
Square root it all and you get
(4+3x)=7
x=1

Why is this so hard for you fags?

answer is 1/7

kek already made it in crypto. And no, I can't solve that problem since I can't remember all the mathematic rules from 7 years ago.

Attached: hqdefault.jpg (480x360, 16K)

are most of these people just fucking around or is biz really that fucking dumb?

because you only took the principal square root you brainlet

(4 + 3x)^2 = 49
4 + 3x = +/- 7
3x = -4 +/- 7
x = -4/3 +/- 7/3

{-11/3, 1}

You are forgetting that (-4-3x)=49 which is -11/3

wtf this makes no sense lmfao how can one variable equal 3 different numbers of one equation brainlet

its not biz fault. This is literally american high school math. While in Europe you learn this stuff in middle school. Thats why American SAT is a joke. My cousin in 9º grade could ace it easy(the math part). And he is average.

Pls tell me you are trolling. And btw its only 2 diferent numbers.

Trolling? He posted 2 different numbers since x has 2 different possible values:
-11/3
1

I think the worst part of their SAT's are that all the questions are only multiple choice and have 0 more difficult problems where they have to show complete work

biz is dumb, just look at archive of the six balls problem thread (3 gold and 3 silver in three boxes)

whatever i was never good at math thats why im in management not basedgineering
