GCF of Polynomials & DOTS

What is the GCF of 18k and 15k³

• 3k²
• 3k³
• 3k
• 5k

Factor the out the GCF

10x² + 15x-5

• 25(10x³+45x-15)

• 5(2x³ + 3x²-x)

• x(10x³+15x-5)

• 5(2x²+3x-1)

 $12c^2-20a^2$  

Factor:

•  $2\left(6c^2-10a^2\right)$  

•  $4\left(3c^2-5a^2\right)$  

•  $2a^2c^2\left(6-10\right)$  

•  $4\left(ca\right)^2\left(3-5\right)$  

What is the first step when factoring polynomials?

• Find the GCF
• List all the terms
• Make a triangle
• Write the answer

Factor the GCF:

4m² - m

• m² (4m - 1)

• m (4m - m)

• m (4m - 1)

• 4m (m - 1)

x² - 9

• (x + 3)²

• (x + 3) (x - 3)

• (x - 3)²

• x + 3(x - 3)

4x² - 25

• (2x + 5) (2x - 5)

• (2x - 5)²

• (2x + 5)²

• 2x + 5(2x - 5)

25x² - 36y²

• 5x + 6y(5x - 6y)

• (5x + 6y) (5x - 6y)

• (5x + 6y)²

• (5x - 6y)²

What is the GCF? 

 $3x^2-2x$  

• 3

• 3x

• x

• 2

8x³ - 18x

• 2x(4x²-9)                                    
• (4x²+3) (2x-3)
• 2x(2x+3) (2x-3)
• PRIME
