Answer:
Step-by-step explanation:
Let the numerator of the fraction=x
Since the denominator of a fraction is two more than the numerator.
Denominator=x+2
The fraction is therefore:
If both numerator and denominator are decreased by six, the fraction becomes:
The simplified result is 
Therefore:
Substituting x=40 into the initial fraction
Therefore, the original fraction is

Answer:
x^3+6x^2-17x+2
Step-by-step explanation:
(x-2)*(x^2+8x-1)
=x(x^2+8x-1)-2(x^2+8x-1)
=x^3+8x^2-x-2x^2-16x+2
collect like terms
= x^3+6x^2-17x+2
