I hope it it help you.

Answer 2

Answer:

STEP

1

:

Equation at the end of step 1

STEP

2

:

9x2 - 4

Simplify ———————

4 - 6x

STEP

3

:

Pulling out like terms

3.1 Pull out like factors :

4 - 6x = -2 • (3x - 2)

Trying to factor as a Difference of Squares:

3.2 Factoring: 9x2 - 4

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 : 9 is the square of 3

Check : 4 is the square of 2

Check : x2 is the square of x1

Factorization is : (3x + 2) • (3x - 2)
