Which shows one way to determine the factors of x3 – 12x2 – 2x + 24 by grouping? pl answerr x(x2 – 12) + 2(x2 – 12) x(x2 – 12) – 2(x2 – 12) x2(x – 12) + 2(x – 12) x2(x – 12) – 2(x – 12)

Step-by-step explanation:

The idea of factoring by grouping is that you don't move anything around.  You leave the polynomial in descending order of powers of x and group them together in groups of 2.

Then you factor out what is common in each set of parenthesis.

You know if factoring by grouping "works" if what's inside both sets of parenthesis is exactly the same.  Both of ours are (x - 12), so grouping "worked".  Match the factoring above to one of your answers.

For anyone else viewing this, the answer is option D.
