Answer:
(x) = 
Step-by-step explanation:
let y = h(x) and rearrange making x the subject, that is
y =
x + 12 ( multiply through by 4 to clear the fraction )
4y = 3x + 48 ( subtract 48 from both sides )
4y - 48 = 3x ( divide both sides by 3 )
= x
Change y back into terms of x, thus
(x) = 
The quotient is 2x^2-5x+2
