8x(5-4x)^3 +33x^2(5-4x)^2 / (5-4x)^6 reduce the following fraction to its lowest terms. An explanation at how you arrived at the answer please ty :)

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

That is what I have.

OpenStudy (anonymous):

did you have to factor the numerator first?

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

Oh i get it. Thanks!
