Find the product.

5x2.2y2

5x2 - 2y2 Answer:

Step-by-step explanation:

3.1 Factoring: 5x2-2y2

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 5 is not a square!

Ruling : Binomial can not be factored as the

difference of two perfect squares
