Answer:


3x^2-8x+9

Explanation:

In this problem, you are adding 2 functions. To do this, simply take the 2 different rules for each function and add them together. This looks like
(2x^2-8x+5)+(x^2+4). Then, to get the final answer remove the parentheses and add like terms. The terms
2x^2 and
x^2 are like while 5 and 4 are also like. If you add
2x^2 and
x^2 you get
3x^2 and 5+4 is 9. Therefore, the final answer is
3x^2-8x+9
