Which shows one way to determine the factors of x3 + 11x2 - 3x - 33 by grouping?

a. x2 (x + 11) + 3 (x - 11)

b. x2 (x - 11) - 3 (x - 11)

c. x2 (x + 11) + 3 (x + 11)

d. x2 (x + 11) - 3 (x + 11)

the answer is D because you can tell because if the negatives and positives at first I thought it was A but if you look at + 3 (x-11) that keeps your 3x positive then if you look at D - 3 (x=11) they both come out as the outcome shown above
