Factoring Trinomials Completely with a Gcf

What is the GCF of the trinomial?
3x² - 9x -120

• 3

• 2

• 6

• 9

What is ALWAYS the first step when factoring?

• Look for the GCF

• Write a, b, and c

• Difference of squares

• Group

Factoring trinomials using a GCF first.
4k²+12k+8

• Prime

• 2(2k+4)(k+2)

• 4(k+2)(k+1)

Factoring Trinomials with GCF (**Slip and Slide Method**) 10x²+75x+35

• 5(x+7)(2x+1)

• 5(x+14)(x+1)

• (x+7)(2x+1)

Factor the trinomial

*start with the GCF

x³ - 6x² + 8x

Factor
2n² + 32n + 126

• (n-7)(n+4)

• (n+7)(n-9)

• (n-3)(n-10)

• 2(n+7)(n+9)

Factor Completely:  5v² - 30v + 40

• (5v - 8)(v + 5)

• (5v + 5)(v - 8)

• 5(v - 4)(v - 2)

• 5(v + 8)(v - 5)
