Question

factorize x^2 -x^2y^2​

Answer 1

Answer:

x2 - x2y2  =   -x2 • (y2 - 1)

(A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

AB = BA is the commutative property of multiplication.

1 is the square of 1

y2  is the square of  y1

=-x2 • (y + 1) • (y - 1)
