Step-by-step explanation:
It is much easier to use the square root method but since you requested the quadratic formula, I will solve it using that method.
First, replace g(x) with 0 for letter c and 11 for letter d. Then simplify and move everything to one side so the equation is equal to zero. Then plug in the a, b, and c values into the quadratic formula to solve for x.
g(x) + 5 = 2x² - 8
c) 0 + 5 = 2x² - 8
0 = 2x² - 13 (subtracted 5 from both sides)
--> 0 = 2x² + 0x - 13 --> a = 2, b = 0, c = -13
d) 11 + 5 = 2x² - 8
0 = 2x² - 24 (subtracted 16 from both sides)
--> 0 = 2x² + 0x - 24 --> a = 2, b = 0, c = -24
