Which shows one way to determine the factors of x^3+11x^2-3x-33 by grouping? a. x^2(x+11)+3(x-11) b. x^2(x-11)-3(x-11) c. x^2(x+11)+3(x+11) d. x^2(x+11)-3(x+11)

The correct answer is D. .

Step-by-step explanation:

To factor the expression by grouping you must:

First, notice that there is no factor common to all terms. However, if we group the first two terms together and the last two terms together, each group has its own greatest common factor.

Second, factor out from :

Next, factor out from :

Therefore,

the value of x is 28.2
