reduce the following fraction to its lowest terms.

An explanation at how you arrived at the answer please ty :)

Answer 1

here is a screen shot of the problem to make it easier

Answer 2

x(5-4x)^2[8(5-4x)+33x]/(5-4x)^4

Answer 3

x[40-32x+33x]/(5-4x)^4
=x[40+x]/(5-4x)^4

Answer 4

That is what I have.

Answer 5

did you have to factor the numerator first?

Answer 6

Factor out a (5-4x)^2 on the numerator, and remove exponents with the denominator

Answer 7

x[40-32x+33x]/(5-4x)^4 =x[40+x]/(5-4x)^4

Answer 8

but when you are factoring the numerator there is a 5-4x^3 and a 5-4x^2

Answer 9

Oh i get it. Thanks!
