Answer:

- 8x + 8

Step-by-step explanation:

(x - 3)² - (x + 1)² ← expand factors using FOIL

= x² - 6x + 9 - (x² + 2x + 1) ← distribute parenthesis by - 1

= x² - 6x + 9 - x² - 2x - 1 ← collect like terms

= - 8x + 8

When given a system of equations, the "solutions" are defined where two equations intersect, or meet.


A. The point where the lines p(x) and g(x) meet is (3, -1), and thus this is considered the solution set.

B. Because there are three lines in total, g(x) is able to intersect both lines one time, and so it has two pairs of solutions.

The first is (3, -1), which has already been established with p(x).

The second is (0, 5), and this is where it intersects with f(x).

C. The solution to f(x) = g(x) is 0, as this is the only x value where both equations are equal.


Hope my answer helped!
