This video tutorial covers factoring quadratic expressions where the leading coefficient is not 1, using a specific method that involves multiplying the leading coefficient and constant term, factoring as usual, and then dividing by the leading coefficient. It also explores special cases such as perfect square trinomials and the difference of squares, providing step-by-step examples to illustrate these concepts.

What is the first step in the factoring method when coefficient 'a' is not 1?

• Divide 'a' by 'c'

• Multiply 'a' with 'c'

• Add 'a' and 'c' together

• Subtract 'c' from 'a'

What should you always check for before starting the factoring process?

• Least common multiple

• Greatest common factor

• Difference of squares

• Perfect square trinomial

In the example, after multiplying 2 by the last term, what is the new expression for factoring?

• 2x^2 + 11x + 24

• x^2 + 11x + 24

• 2x^2 + 11x + 12

• x^2 + 11x + 12

What is the result of factoring the expression x^2 + 11x + 24?

• (x + 24)(x + 1)

• (x + 12)(x + 2)

• (x + 4)(x + 6)

• (x + 8)(x + 3)

What defines a perfect square trinomial?

• a^2 - ab + b^2

• a^2 + 2ab + b^2

• a^2 + ab + b^2

• a^2 - 2ab + b^2

What is the formula for the difference of two squares?

• a^2 - b^2 = (a + b)(a - b)

• a^2 + b^2 = (a + b)^2

• a^2 + b^2 = (a + b)(a - b)

• a^2 - b^2 = (a - b)^2
