Answer:
R(X) = -27x^2 + 14x + 4
Step-by-step explanation:
f(x) = 2x^2 + 7x - 28x^2 - 16
Combine like terms
f(x) = -26x^2 + 7x - 16
now for g(x)
g(x) = 7x + 4 - x^2 + 16
g(x) = -x^2 + 7x + 20
Now to solve the main equation
R(x) = --26x^2 + 7x - 16 - x^2 + 7x + 20
Combine like terms
R(x) = -27x^2 + 14x + 4
Hope this helped!
