Factoring Polynomial Expressions

Factor:  x² + 13x + 30

• (x + 3)(x + 10)

• (x + 5)(x + 6)

• (x + 2)(x + 15)

• (x + 1)(x + 30)

Factor: x² - 16x + 28

• (x + 2)(x - 14)

• (x - 2)(x - 14)

• (x + 14)(x - 2)

• (x - 4)(x - 6)

Factor by grouping.

2x² - 5x + 2

• (2x - 1)(x - 2)

• (2x + 1)(x - 2)

• (2x - 2)(x - 1)

• (2x + 2)(x - 1)

Factor by grouping.

4x² - 16x + 15

• (2x + 3)(2x - 5)

• (4x + 3)(x - 5)

• (2x - 3)(2x - 5)

• (4x - 3)(x + 5)

If a = 4x and b = 5, write a SUM of Cubes Problem that would need to then be factored.

Match each polynomial to its factored form:

• (x-4)(x+1)

• (x-4)(x-1)

• (x+4)(x+1)

• (x+4)(x-1)

Factor by grouping.

8x² + 31x - 4

• (8x - 1)(x + 4)

• (4x - 1)(2x + 4)

• (2x - 1)(4x + 4)

• (8x - 2)(x + 2)
