Factor the equation.
barxatty [35]
X² - 11x + 18

find factors of x² and 18 that will give you -11x

x² - 11x + 18
x               -9
x               -2

(x - 9)(x -2) is your answer

if you are finding the x, place each parenthesis equal to zero

x - 9 = 0
x - 9 (+9) = 0 (+9)
x = 9

x - 2 = 0
x - 2 (+2) = 0 (+2)
x = 2

x = 2, 9
