Question

8xy^3*xy ^8 plsssssssssssssssssssss help

Answer 1

x • (x^3 - 3x^2y + 3xy^2 + 7y^3)

Explanation:

(8x • (y^3)) + x • (x - y)^3

2^3xy^3 + x • (x - y)^3

Evaluate : (x-y)^3 = x^3-3x^2y+3xy^2-y^3

Pull out like factors :

x^4 - 3x^3y + 3x^2y^2 + 7xy^3 =

x • (x^3 - 3x^2y + 3xy^2 + 7y^3)

x^3 - 3x^2y + 3xy^2 + 7y^3 is not a perfect cube
