Question

If a(x) = 2x - 4 and b(x) = x + 2, which of the following expressions produces a quadratic function

Answer 1

Explanation:

Multiplying a(x) and b(x) together results in a quadratic equation (a trinomial). This trinomial looks like (a·b)(x) = (2)(x - 2)(x + 2). Note that this is a "special product;" (2)(x^2 - 4); there is no middle term.

Answer 2
