Polynomials and Factoring Pretest

Solve by factoring: 5x² + 13x + 6 = 0

• x = -2 and x = -3/5

• x = 2 and x = 3/5

• x = -2 and x = 3/5

• x = 2 and x = -3/5

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 out the GCF:
12x + 6

• 6(2x + 1)

• 3(4x + 2)

• 6x(2x + 1)

• 2(6x + 3)

3x²+9x-30=0

• x= 2, -5

• x= 5, -2

• x= -5, -2

The GCF of 2x²-4x+8 is (a)   .

• 2x

• 2

• x

• 1

If a = 4x and b = 5, write a SUM of Cubes Problem that would need to then be factored.
