Question

Factor completely 7x3y +14x2y3 − 7x2y2.

Answer 1

7x^2y(x +2xy^2 -y)

Explanation:

7x^3y +14x^2y^3 − 7x^2y^2

WE find out GCF

7x^3y= 7*x*x*x*y

14x^2y^3= 7*2*x*x*y*y*y

7x^2y^2 = 7 *x*x*y*y

GCF is 7x^2y

Factor out GCF from the given expression. when we factor out 7x^2y we divide each term by GCF. we put GCF 7x^2y outside

7x^2y(x +2xy^2 -y)

Answer 2

7x^2y(x +2xy^2 -y)

Explanation:

7, x^2, and y are factors of every term, so we can start by factoring those out.

... = 7x^2y(x +2xy^2 -y)

The trinomial does not factor further, so this is it.
