Using the polynomials q = 3 x2 + 5 x - 2, r = 2 - x2 , and s = 2 x + 5, perform the indicated operation. q - [ r + s ]

4x^2 + 3x - 9

Step-by-step explanation:

First, add together functions R(x) and S(x).  Stack them vertically and combine like terms:

R(x) = 2 - x^2

S(x) = 2x + 5

(R+S)(x) = -x^2 + 2x + 7

Now subtract the above result from Q(x):

Q(x) - (R(x) + S(x)) =  3x^2 + 5x - 2  + x^2 - 2x - 7, or 4x^2 + 3x - 9
