What is the GCF? 5x²+20x

• 5
• x
• 5x
• 20x

Factor out the GCF:

8r³ + 16r²

• 4r²(2r + 4)

• 8r²(r + 2)

• 8(r³ + r²)

• 4(r³ + 2r²)

Factor out the GCF:

8n³ + 2n²

• 2n²(4n-1)

• 2n²(4n + 1)

• n²(8n+2)

• 3n(4n+1)

Factor: x²-17x+72

• (x-9)(x+8)

• (x-9)(x-8)

• x(x-3)

• (x+9)(x+8)

Factor: x²-7x-8

• (x+1)(x-8)

• (x+1)(x+8)

• 5(x+4)(x+5)

• (x-1)(x+8)

Factor: x²+13x+40

• (x+5)(x+8)

• 5x(x+3)

• 3x(x+6)

• x(x-4)

Factor:

x² + 9x − 36

• (x + 12)(x − 3)

• (x + 9)(x − 4)

• (x − 12)(x + 3)

• (x − 9)(x − 4)

What is the first step when factoring polynomials?

• Find the GCF

• List the a, the b, and the c

• Make a triangle

• Write the answer

Factor completely.
k² -2k - 24

• (k + 4)(k - 6)

• (k + 4)(k + 6)

• (k + 6)(k - 1)

• (k - 4)(k + 6)
