Question

(12x^2-4x-8)/4x

Answer 1

that's better and clear now
we divide each term by the denominator and get
(3x - 1) - 2/x

or we can put answer as (3x^2 - x - 2)/x

Answer 2

(12x^(2)-4x-8)/(4x)

(4(3x^(2))+4(-x)+4(-2))/(4x)

(4(3x^(2)-x-2))/(4x)

(4(x+(2)/(3))(x-1))/(4x)

4(3x+2)(x-1)/(4x)

(3x+2)(x-1)/(x)
