The video tutorial covers the process of factoring quadratic equations, particularly when the leading coefficient is not equal to one. It begins with an introduction to quadratics and the importance of factoring. The instructor explains the use of the greatest common factor (GCF) and introduces two methods for factoring: the AC method and a mental math approach. The AC method is detailed, showing how to break down the quadratic into simpler parts. The mental math technique is presented as a quicker alternative for solving these problems. The video emphasizes checking solutions by multiplying factors back together.

What is the first step recommended when factoring a quadratic equation where the leading coefficient is not 1?

• Use the quadratic formula

• Graph the equation

• Factor out the greatest common factor (GCF)

• Find the roots of the equation

In the AC method, what do you need to find two numbers that multiply to?

• a * c

• b * c

• b + c

• a + c

When using the AC method, what should the two numbers add up to?

• a

• b

• a * c

• c
