Question

Product of (2x-2y)(x+2y)

Answer 1

By distributive property
\[\Large (2x-2y)(x+2y)=(2x)(x)+(2x)(2y)+(-2y)(x)+(-2y)(2y)\]
\[\Large= 2x ^{2}+4xy-2xy-4y ^{2}\]
\[\Large=2x ^{2}+2xy-4y ^{2}=2(x-y)(x+2y)\]

Answer 2

use FOIL. F-first O-outer I-inner L-last.

Answer 3

once you reduce it down or simplify- The answer is x^2 + xy - 2y^2.

Answer 4

(2x−2y)(x+2y)

=(2x+−2y)(x+2y)

=(2x)(x)+(2x)(2y)+(−2y)(x)+(−2y)(2y)

=2x^2+4xy−2xy−4y^2

=2x^2+2xy−4y^2

Just use FOIL.
