Factoring Practice

Factor
3v² - 4v - 7

• (3v-7)(v+1)

• 3(v-7)(v-1)

• (3v+1)(v-9)

• (3v+1)(v-10)

What is the GCF of the trinomial?
3x² - 9x -120

• 3

• 2

• 6

• 9

• two numbers that multiply to give you -10 and add to give you 16

• two numbers that multiply to give you 16 and add to give you 10

• two numbers that multiply to give you 16 and add to give you -10

• two numbers that multiply to give you -16 and add to give you -10

When factoring the polynomial, what are you trying to find?

• two numbers that add to give you 8 and multiply to give you 6

• two numbers that multiply to give you 8 and add to give you 6

• two numbers that multiply to give you 8 and multiply to give you 6

• two numbers that add to give you 8 and add to give you 6

What do you do to the b value to correctly complete the square?

• square it

• divide it by 2 and square the result

• divide it by 2 and take the square root of the result

• divide it by 2 only
