Question

Which of the following, when multiplied by x – 1, results in a cubic polynomial whose standard form has three terms?

a. (x – 1)^2
b. x^2 – x
c. x^2 – 1
d. x – 1

Answer 1

b.

Explanation:

Looks like it's b because they wont be a constant term at the end.

(x - 1 )(x^2 - x)

= x^3 - x^2 - x^2 + x

= x^3 - 2x^2 + x.
