What is the product of ( 8p + 11 )( 8p - 11 )?

• 8p² - 22

• 16p² - 22

• 64p² - 121

• 64p² - 88p - 121

Multiply: ( 4k + 3 )( 3k² - 3k + 1 )

• 12k³ - 3k² - 5k + 3

• 12k³ + 3k² + 5k - 3

Factor:
10x + 15

• 100x + 150

• 10(x + 5)

• 1(10x + 15)

• 5(2x + 3)

If a leading coefficient is negative, before factoring I should

• use AC!

• factor out the negative

Factor

8x²-56x+48

My first step is to

• AC!

• Factor out GCF

• Use SUM & DIFFERENCE

• USE SQ OF A BINOMIAL
