B. 2(x - 1)(x + 6)
C. 2(x - 6)(x + 1)

Answer 1

2x2-12x+2x-122x(x-6)+2(x-6)(2x+2)(x-6)2(x+1)(x-6)the answer is C

Answer 2

the answer is the c 2(x-6)(x+1)

Explanation:

First you take the common factor

2(x^2) - 2(5x) -2(6)

2(x^2 - 5x - 6)

you search two numbers that the sum are -5 but when you multiply it is -6

The numbers are -6 and +1

you can reduce it as follows

2(x-6)(x+1)
