**QUIZ** Factoring Polynomials

Factor:
x² + 7x - 30

• (x + 10)(x - 7)
• (x - 10)(x + 3)
• (x + 10)(x + 3)
• (x + 10)(x - 3)

To begin factoring x² + 13x + 42, we set ourselves up by thinking of two numbers that (blank) to 42 and (blank) to 13.

• multiply, add -or- subtract

• add -or- subtract, multiply

• add -or- multiply, subtract

• subtract -or- multiply, add

• 

Factor: 4b⁵+4b³+16b²
