Question

Please help me. I can't figure this out. I've been doing math for 5 hours and that's not an exaggeration.

Answer 1

Well you have to do PEMDAS

So we have an exponent so that will turn into a positive X

X+4x=10

So now we combine our X's together to get 5X=10

Now we divide both sides by X which gives us 2

Sorry read the problem wrong

Ask questions if you still need help :)

Answer 2

-1 (X^2 - 4x = 10)

First divide by negative 1

-( x^2 - 4x + 4 = 10 + 4)

Second create a perfect square

(x - 2)^2 = 14

Third factor and add like terms

sqrt/ (x - 2)^2 = sqrt/ 14

Fourth find the square root of both sides

x - 2 = (+\-) sqrt/14

Fifth remember to factor in that the answer could be positive or negative!

x = 2 (+/-) sqrt/14

Sixth add two to both sides and conclude your answer is two plus or minus the square root of fourteen.
