Question

How do i find x from the equation x(x+6)=108

Answer 1

x = -3 + √117

x = -3 - √117

Explanation:

So the equation is x(x+6)=108

first you gotta simplify

x*x + x*6 = 108

x^2 + 6x = 108

x^2 + 6x - 108 = 0

using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a) with a=1, b=6 and c=-108
