Factoring Practice

Factor
d² - 10d + 25

• (d + 5) (d - 5)

• (d - 15) (d + 10)

• (d + 5) (d - 20)

• (d - 5) (d - 5)

Which of the following is a factor of x²-10x+24?

• x-4

• x+4

• x+6

• x-2

• (x-8)(x+3)

• (x-8)(x+5)

• (x-3)(x-8)

• (x-6)(x-4)

What is the GCF of the trinomial?

• 3

• 3x

• -3

• 9

Factor Trinomial Completely:
2x² + 12x + 16

• 2(x + 8)(x + 6)

• (2x + 4)(2x + 2)

• 2(x + 2)(x + 4)

• 2(x² + 6x + 8)

Factor completely:
3x² + 18x +15
Hint: Factor GCF first.

• 3(x² + 6x + 5)

• (x + 5)(x + 1)

• 3(x + 5)(x + 1)

• Prime
