d
11x - 6

D

Step-by-step explanation:

3(2x-2)+5x

11x-6

  x • (x2 - 2x - 5)

Step-by-step explanation:

3.2     Factoring  x2 - 2x - 5  

The first term is,  x2  its coefficient is  1 .

The middle term is,  -2x  its coefficient is  -2 .

The last term, "the constant", is  -5  

Step-1 : Multiply the coefficient of the first term by the constant   1 • -5 = -5  

Step-2 : Find two factors of  -5  whose sum equals the coefficient of the middle term, which is   -2 .

     -5    +    1    =    -4  

     -1    +    5    =    4  

So D
