Question

Factor x3 – 4x2 + 7x – 28 by grouping. What is the resulting expression?

(x2 – 4)(x + 7)
(x2 + 4)(x – 7)
(x2 – 7)(x + 4)
(x2 + 7)(x – 4)

Answer 1

Is this the expression?

\[x ^{3}-4x ^{2}+7x-28\]

Answer 2

First group them with parentheses in such a way that the terms you put inside have a common factor.
In this case, the first set of parentheses have an x^2 in common. The second set have a 7 in common.

\[(x ^{3}-4x ^{2})+(7x-28)\]
