Factoring Perfect Square Trinomials

The video tutorial explains how to factor perfect square trinomials using specific strategies. It begins with examples where the coefficient A is equal to 1, demonstrating the process of identifying perfect squares and factoring them into binomials. The tutorial then progresses to more complex examples where A is not equal to 1, emphasizing the importance of recognizing perfect squares in the first and third terms. The video concludes with a summary of the key steps and a reminder to verify the results by checking the sum of the inner and outer products.

What is the first step in factoring a perfect square trinomial when 'A' equals 1?

• Multiply the first and last terms.

• Identify the factors of the middle term.

• Find the factors of the constant term that add to the middle term.

• Divide the trinomial by the middle term.

Why is 64 considered a perfect square in the context of factoring trinomials?

• Because it is a multiple of 8.

• Because it can be expressed as 8 x 8.

• Because it is an even number.

• Because it is less than 100.

When factoring trinomials with 'A' not equal to 1, what must be true about the first and third terms?

• They must be multiples of 10.

• They must be prime numbers.

• They must be perfect squares.

• They must be even numbers.
