Factoring using a perfect square trinomial when a is not 1

The video tutorial explains the process of factoring trinomials, focusing on identifying perfect square trinomials. It begins by discussing why certain techniques, like the difference of squares, are not applicable. The instructor then guides through the steps to break down the expression, ensuring the factors meet specific conditions. The process is verified by checking the inner terms, confirming the factorization as a perfect square trinomial.

Why can't the expression be a difference of two squares?

• Because it has more than two terms.

• Because it is not separated by addition.

• Because it has a square term in the front.

• Because it is a perfect square trinomial.

What assumption is made about the terms in the factoring process?

• They must be positive.

• They must be equal.

• They must be integers.

• They must be negative.

What is the result of multiplying 4X by 4X?

• 16X^2

• 4X^2

• 8X

• 16X

What is the factored form of the expression?

• (4X + 3)(4X - 3)

• (4X - 3)(4X + 3)

• (4X - 3)^2

• (4X + 3)^2

How do we verify that the expression is a perfect square trinomial?

• By confirming the inner terms add to give the correct middle term.

• By checking if the expression is a difference of squares.

• By ensuring the middle term is zero.

• By checking if the outer terms add to give a positive number.
