Factoring Busting B

What is the GCF of 28ab and 42b

• 4b

• 6b

• 7b

• 14b

Factor using GCF:

10x³ + 15x² - 5x

• 25(10x³ + 45x - 15)

• 5(2x³ + 3x² - x)

• x(10x³ + 15x - 5)

• 5(2x² + 3x - 1)

Can 5x + 33 be factored? Explain, why or why not.

• yes

• no

When using factor by grouping, how many terms must we have?

• Four

• Two

• Three

• Doesn't matter

Factor:

7r^{3 +} 6r² + 42r + 36

• (r² + 6)(7r + 8)

• (r² + 6)(7r - 8)

• (r² + 6)(r² + 8)

• (r² + 6)(7r + 6)

Factor:

x³ + 4x² - 4x - 16

• (x + 4)(x + 2)

• (x - 4)(x² - 4)

• (x + 4)(x² - 4)

• (x - 4)(x - 2)

Factor Completely: x² + 13x + 40

• (x + 5)(x + 8)

• 5x(x + 3)

• 3x(x + 6)

• x(x - 4)

Factor
x² + 9x - 36

• (x + 12)(x - 3)
• (x + 9)(x - 4)
• (x - 12)(x + 3)
• (x - 9)(x - 4)

Factor

r² -16r + 60

• (r - 15)(r + 4)

• (r - 6)(r + 10)

• (r - 6)(r - 10)

• (r + 30)(r - 2)

Factoring is the opposite of which property

• associative

• additive inverse
