Factor Trinomial a=1 Using x

Factor the Trinomial:

x² - 17x + 72

• (x - 9)(x + 8)

• (x - 9)(x - 8)

• x(x - 3)

• (x + 9)(x + 8)

Factor the Trinomial:

9x²-6x-8

• (3x+2)(3x-4)

• (3x+2)(3x+4)

• (3x-2)(3x-4)

• (x-1)(9x+8)

Factor the Trinomial:

5x² + 17x + 6

• (5x + 3)(x + 2)

• (5x + 2)(x + 3)

• (5x + 1)(x + 6)

• (5x + 6)(x + 1)

To factor a trinomial by grouping, start by...

• multiplying the "a" term times the "c" term and identifying the "b" term

• saying a quick prayer

• multiplying the "b" term times the "c" term and identifying the "a" term

• multiplying the "x" term times the "y" term and identifying the "m" term

• (x + 5)(x + 5)

• (x + 25)(x + 1)

• (x - 5)(x - 5)

• (x + 5)(x - 5)

When factoring trinomials by grouping, after you multiply the "a" and the "c" term and identify the "b" term, use these 2 values as clues to find:

• 2 numbers that subtract to "a" times "c" and add to "b"

• 2 numbers that divide to "a" times "c" and add to "b"

• 2 numbers that sum to "a" times "c" and subtract to "b"

• 2 numbers that multiply to "a" times "c" and add to "b"
