2 • (4x2 - 3x - 4)

Step-by-step explanation:

(23x2 - 6x) - 8

STEP

STEP

3

:

Pulling out like terms

3.1 Pull out like factors :

8x2 - 6x - 8 = 2 • (4x2 - 3x - 4)

Trying to factor by splitting the middle term

3.2 Factoring 4x2 - 3x - 4

The first term is, 4x2 its coefficient is 4 .

The middle term is, -3x its coefficient is -3 .

The last term, "the constant", is -4

Step-1 : Multiply the coefficient of the first term by the constant 4 • -4 = -16

Step-2 : Find two factors of -16 whose sum equals the coefficient of the middle term, which is -3 .

-16 + 1 = -15

-8 + 2 = -6

-4 + 4 = 0

-2 + 8 = 6

-1 + 16 = 15

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

2 • (4x2 - 3x - 4)
