Intro to Factoring

Factor completely: x²-13x+40

• (x-5)(x-8)

• (x+5)(x+8)

• (x-4)(x-10)

• (x-2)(x-20)

What number should go where the question mark is?

What terms should do where the two question marks are?

• -3x

• 3x

• -2x

• 2x

• 6x

What term goes where the question mark is?

Looking at the completed problem, what are the two factors?

• (x-2)

• 3x and -2x

• (x+3)

• 6x³y²

• 6x⁹y⁶

Factor: 10x + 15

An example of your Box Method is set up to the left.

• 100x + 150

• 10(x + 5)

• 1(10x + 15)

• 5(2x + 3)

Factor: x² - 5x

An example of your Box Method set up is to the left

• 1(x - 5)

• x(x - 5x)

• x(x - 5)

• x²(1 - 5)

Factor: 24c⁵ - 12c³

An example of your Box Method is set up to the left.
