Answer:
The solutions of this system of equations are (-2, -2) and (1, 1).
Step-by-step explanation:
Let be the following system of equations:
(1)
(2)
(2) in (1):


This polynomial can be solved analytically by Quadratic Formula:
, 
Hence, the solutions of this system of equations are (-2, -2) and (1, 1).
(f+g)(x) just means f(x) + g(x)

Choice B
Answer:
Step-by-step 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.
