What is the GCF (MCD) of 18k and 15k³

(Use a tree or prime factorization)

• 3k²

• 3k³

• 3k

• 5k

Factor out the GCF (Factorizar sacando el MCD)

3x³ + 9x

• 3x (x² + 3)

• 3x ( x³ + 9)

• x (3x² + 9)

• 3x (x³ + 3x)

Factor Completely

12abc + 18ab²c - 6b

• 6b (2abc + 3b - 1)

• 6b ( 2ac + 3abc - 1)

• 6b (2ac + 3abc)

• 6abc (2 + b)

• 12

• 18

• 36

• 24

Factor by GCF twice!

7r³-8r²+42r-48

• (r²+6)(7r+8)

• (r²+6)(7r-8)

• (r²+6)(r²+8)

• (r²+6)(7r+6)

Factor by GCF twice!

5n³-10n²+3n-6

• (5n²+3)(n-2)

• (5n²-3)(n-2)

• (5n³+3)(n-2)

• 10n(n²-6)

Factor
x² – 5x – 24

• (x - 5)(x + 19)
• (x - 8)(x + 3)
• (x - 3)(x + 8)
• (x - 19)(x + 5)
