Factoring by GCF

What is the first step when factoring polynomials?

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

Factor out the GCF
10x + 15

• 100x + 150
• 10(x + 5)
• 1(10x + 15)
• 5(2x + 3)

Factor:

17xy - x

• 17(xy - x)

• y(17x - x)

• x(17y - 1)

• x(17y)

Factor:

5x³ - 7x²

• x²(5x - 7)

• x(5x² - 7x)

• x³(5 - 7x)

• Prime

Factor:
x² - 10x + 24

• (x - 6)(x - 4)
• (x + 6)(x + 4)
• (x - 12)(x + 2)
• (x - 8)(x - 3)

Find GCF of 22x³+11x²

• 11x
• 11x²
• 22x
• 22x²

FACTOR
7w³-14w

• 7w(w²-2)
• 7w(w²-2w)
• 7w(w-2)
• 7w(w+2)

Factor 12x - 20

• 6(2x - 3)

• 4(3x - 5)

• 4x(3x - 5)

• 3(4x + 6)

Factor:  
4x + 30y

• 2(x + 15y)
• 4(x + 15y)
• 2(2x + 15y)
• can't be factored
