Factor using the ac method

3v² - 4v - 7

• (3v-7)(v+1)

• 3(v-7)(v-1)

• (3v+1)(v-9)

• (3v+1)(v-10)

Factor out the greatest common factor

7w³-14w

• 7w(w²-2)

• 7w(w²-2w)

• 7w(w-2)

• 7w(w+2)

Factor out the GCF:
10x³ - 15x

• x(10x² - 15)
• 5x(2x² - 3)
• 5(2x³ - 3x)
• 5x²(10x - 3)

Factor by grouping

5n³-10n²+3n-6

• (5n²+3)(n-2)

• (5n²-3)(n-2)

• (5n³+3)(n-2)

• 10n(n²-6)

Which answer correctly factored for the equation below?

• (x + 7)(x - 2) = 0
• (x - 7)(x + 2) = 0
• (x - 7)(x - 2) = 0
• (x + 7)(x + 2) = 0
