Answer 1

Answer:

(7x+6    )  ( x -2   )

Step-by-step explanation:

7x^2 -8x-12

(7x    )  ( x    )

What are the factors of -12

-1*12       1 * -12

-2*6          2 * -6

-3*4           3 * -4

Something * 7 + something = -8

We need to fill in   with the factors

-2 * 7 + 6 = -8

-14 -6 = -8  True

7x^2 -8x-12

(7x+6    )  ( x -2   )

Answer 2

Split the second term 7x^2 - 8x - 12 into two terms

7x^2 + 6x - 14x - 12

Factor out common terms in the first two terms, then in the last two terms

x(7x + 6) - 2(7x + 6)

Factor out the common term; 7x + 6

(7x + 6)(x - 2)
