Factoring Trinomials Using the X Method

Factor:
6k² - 19k - 7

• (k + 7)(6k - 1)

• (2k + 1)(3k - 7)

• (3k - 1)(2k - 7)

• (3k + 1)(2k - 7)

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

• 3

• 2

• 6

• 9

Factor completely.
2n² + 13n + 15

• (5n - 9)(n - 3)

• (3n + 7)(n + 4)

• (2n + 3)(n + 5)

• Not factorable

Factor 2X² +5X + 2

• (X+1)(X+2)

• (2X+1)(X+2)

• (X+1)(2X+5)

• (2X+1)(2X+2)

(X-2)(X-3) is equal to:

• X² -5X +6

• X² -5X - 6

• X² +5X +6

• X² +5X -6

Factoring trinomials (slip and slide method)

8y²-10y-3

• Prime

• (2y-3)(4y+1)

• (2y+1)(4y-3)

• (4y-1)(2y+3)

What formula do we use to identify the "a", "b", and "c" when factoring?

• ax² +bx + c

• ax² +cx + b

• bx² +ax + c

• cx² +bx + a

To factor the trinomial 6x² + 11x +3, start by multiplying "a" times "c" and identifying "b".

• true

• false

• 9 and -2

• 9 and 2

• -9 and -2

• -9 and 2

To factor 2x² +11x + 5, write the middle term using the 2 numbers that multiply to ___ and add to ___, make sure to include the "x". Write it like this:

*Choose 2 that apply.

• 10; 11; 2x² + 5x +2x + 5

• 22; 5; 2x² + 9x +2x + 5

• 10; 11; 2x² + 10x +x + 5

• 10; 11; 2x² + x +10x + 5
