Question

The domain for f(x) and g(x) is the set of all real numbers.

Let f(x) = 2x^2 + x - 3 and g(x) = x-1
Find f(x) • g(x).​

Answer 1

2x^3-x^2-4x+3

Explanation:

Answer 2

`2x^3-3x^2-4x+3`

Explanation:

Use FOILing to get the answer. Distribute x into 2x^2, to get 2x^3, then into x to get - x^2, then into -3 to get -3x. Then distribute the -1 into the 2x^2 to get -2x^2, then into the x to get -x, then into the -3 to get 3. Combine like terms to get the solution above.
