Gcf and Differ

What does GCF mean?

• green colored frogs

• greatest coefficient

• greatest common factor

• greater common fraction

• (x - 5)

• (x - 5x)

• (x - 5)

• ²(1 - 5)

• 2n²(4n-1)

• 2n²(4n + 1)

• n²(8n+2)

• 3n(4n+1)

Factor by using GCF:
Remember that the answer should be written as GCF(quotient)

• 25(10x³ + 45x - 15)

• 5(2x³ + 3x² - x)

• x(10x³ + 15x - 5)

• 5(2x² + 3x - 1)

• Yes, because the teacher is always right!

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

What is ALWAYS the first step when factoring?

• Look for the GCF

• Write a, b, and c

• Difference of squares

• Group

• x(3x² + 9x - 15) 

• 3x(x² + 3x - 5)

• 3x(x² - 9x + 15) 

• x(3x² -9x + 15) 

what is the greatest common factor of the three terms in the expression
-24m³n⁵p + 24mn⁴p² + 4mn⁵

• 4mn

• 24mn⁴

• 4mn⁴

• 4mn⁴p

Factor out the GCF: 7x² - 14x

• 7(x² - 2x)

• 7x²(x - 2)

• 7x(x - 2)

• 7x(x - 14)

Factor out the GCF:

8x - 16

• 8(x - 2)

• 8x(x - 2)

• 16(x - 1)

• 8x(1 - 2)
