Learn to solve a quadratic by factoring a=1

The video tutorial explains how to factor a trinomial, specifically a perfect square trinomial, using the X method. It covers the process of identifying factors of the constant term that add up to the linear coefficient, and applying the zero product property to solve the equation. The tutorial emphasizes understanding the method when the leading coefficient is one and concludes with a demonstration of solving the trinomial.

What is the initial trinomial expression discussed in the video?

• y = X^2 + 15X + 75

• y = X^2 + 20X + 100

• y = X^2 + 10X + 50

• y = X^2 + 25X + 125

When using the X method, what are the two numbers that multiply to give AC and add to give B?

• 25 and 4

• 10 and 10

• 15 and 5

• 5 and 20

What is the value of 'a' in the trinomial y = X^2 + 20X + 100?

• 0

• 10
