2. 1.3,1 1/3, 1.34 __________
3. 2.07,2 7/10,2.67, -2.67 _____________________
Answer:
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
