You can find the zeros only when the nominator is equal to 0
So it's not necessary to care about the denominator in here
x 2 - x - 12 = 0
You can solve by factorisation, quadratic formula, or completing square
( x - 4 ) ( x + 3 ) = 0
And you can solve it
You get x= 4 and x= -3

f ( x ) = x 2 - x - 12 x - 2
= ( x + 3 ) ( x - 4 ) x - 2
f ( x ) = 0 ( x + 3 ) ( x - 4 ) x - 2 = 0
