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 :)
-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.
