Trying to factor as a Difference of Squares

2.1 Factoring: 49h2-225

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 : 49 is the square of 7

Check : 225 is the square of 15

Check : h2 is the square of h1

Factorization is : (7h + 15) • (7h - 15)
