Answer:

12y3 - 4y

Step-by-step explanation:

How to solve your problem

4y (3y2 - 1)​

Step 1. Equation at the end of step 1

4y (3y2 -1)

Step 2. Trying to factor as a Difference of Squares:

2.1 Factoring 3y2-1

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: 3 is not a square

Ruling : Binomial can not be factored as the

difference of two perfect squares

Final result :

4y • (3y2 - 1)
