Factor GCF
 $10a^4-100a^3+20a^2$  

•  $2a^2\left(3a^3-10a+2\right)$  

•  $10a^2\left(3a^2-10a+2\right)$  

•  $10a^2\left(3a^4-10a^3+2a\right)$  

•  $10a^2\left(3a^3-10a+2\right)$  

Factor completely

21x⁷y⁶ + 30x⁵y⁸ - 18x⁵y⁶

• 3xy (7x⁴y² + 10x²y⁶ - 6x)

• 3x⁵y⁶ (7y² + 10 x² - 6)

• 3x⁵y⁶ (7x² + 10y² - 6)

• 3x⁷y⁸ (7y² + 10x² - 6x²y²)

Solve by factoring:  2x²+ 7x + 6 = 0

• x= 3/2 and x = 2
• x = -3/2 and x = -2
• x = 6 and x = 7
• x = -6 and x = -7
