f(x) = {x}^(2) - x - 6


f(x) = (x - 3)(x + 2)


0 = (x - 3)(x + 2)

_________________________________

Hint :


a * b = 0


a = 0 \: \: \: or \: \: \: b = 0

_________________________________

Thus ;


x - 3 = 0

Add sides 3


x - 3 + 3 = 0 + 3


x = 3

Or


x + 2 = 0

Subtract sides 2


x + 2 - 2 = 0 - 2


x = - 2

Thus the x-intercepts are (( - 2 )) and (( 3 )) .
