The first step in determining the solution to the system of equations, y = –x2 – 4x – 3 and y = 2x + 5, algebraically is to set the two equations equal as –x2 – 4x – 3 = 2x + 5. What is the next step?
Answer
A
Set y = 0 in y = –x2 – 4x – 3.
B
Factor each side of the equation.
C
Use substitution to create a one-variable equation.
