Factor Binomials Using Gcf

Factor Completely: 
x⁴-9x²
Hint: Factor GCF first. 

• x²(x+3)(x-3)

• (x²+3x)(x²-3x)

• (x²+9)(x-3)(x+3)

• x²(x²-9)

Factor Completely: 
3x⁵ - 27x³
Hint: Factor GCF first. 

• 3(x³ - 3)(x² + 3)

• prime

• 3x³(x² - 9)

• 3x³(x - 3)(x + 3)

Factor by GCF:

6x² + 16x

Factor using the GCF : -21x+35

• -7(3x - 5)

• 7(-21x² + 35)

• 28(-3x² + 5x)

• 7(3x - 5)

• Yes, because the teacher is always right!

• No, because 9 doesn't divide into 18 and 36. There are too many variables.
