Factoring Binomial Using Gcf

Factor 7x + 21 using the GCF

• 7(x+3)

• 7x + 3

• 3(x + 7)

• x(7 + 3)

Factor:
10x + 15

• 100x + 150

• 10(x + 5)

• 1(10x + 15)

• 5(2x + 3)

Factor 12x - 40 using the GCF

• 2 (6x -20)

• 4 (3x + 10)

• 4 (3x - 10)

• 2 (6x + 20)

Factor 24x - 64 using the GCF

• 12 (2x - 5)

• 6 (4x - 12)

• 8 (3x - 8)

• 24 (x - 3)

• Yes, because the teacher is always right!

• No, because 9 doesn't divide into 18 and 36. There are too many variables.

What is the first step when factoring polynomials?

• Find the GCF

• List all the terms

• Make the X and fill in the top and bottom

• Multiply a and c

Factor by GCF:

18a²-15a

• 15a(3a-1)

• 3a(6a-1)

• 3(6a-5)

• 3a(6a-5)

Factor 12x² - 2xy - 4y²

• Take out the GCF

• Factor the rest by any method (x-game, slide & divide and magic square). Final answer should contain the GCF

Factor: 8x² - 32.

• Take out the GCF

• Factor again the left over using difference of squares.

• 1(x - 5)

• x(x - 5x)

• x(x - 5)

• x²(1 - 5)
