How to factor a perfect square trinomial and why is it important

The video tutorial explains different methods of factoring, focusing on perfect square trinomials. It reviews the AC method and introduces a technique for identifying and factoring perfect square trinomials. The instructor provides a step-by-step example and discusses how to apply these methods to more complex problems. The tutorial concludes with a summary of the methods and tips on when to use them.

What is the primary method discussed for factoring in the initial part of the lesson?

• Completing the Square

• Synthetic Division

• AC Method

• Quadratic Formula

Which of the following represents a perfect square trinomial?

• x^2 + 4x + 4

• x^2 + 2x + 1

• x^2 + 5x + 6

• x^2 - 3x + 2

In the formula for a perfect square trinomial, what does the middle term represent?

• Twice the product of the square roots of the first and last terms

• The difference of the squares

• The sum of the squares

• The product of the roots

What is the factored form of the trinomial x^2 - 10x + 25?

• (x + 5)^2

• (x - 5)^2

• (x - 10)(x + 2.5)

• (x - 2.5)^2

When dealing with a trinomial like 36x^2 - 60x + 25, what should you verify to use the perfect square trinomial method?

• The trinomial is divisible by 3

• The middle term is a prime number

• The first and last terms are perfect squares and the middle term is twice the product of their roots

• The coefficients are all even numbers
