Question

Plz help, im not sure how to do this...

Answer 1

square both sides first then solve the quadratic equation

Answer 2

so i have \[100x=x^2+32x+256\]

Answer 3

You have \[x^2 - 68x + 256\]
Use middle term factorization or \[x=(−b±\sqrt{b^2 - 4ac})\div (2a)\]

where \[ax^2 + bx + c\] is the equation in which a= 1, b = -68 , c =256 to get the roots

Answer 4

so the answers are 64 and 4 right?

Answer 5

yes

Answer 6

yay!
