Answer:

[tex]3x^2-8x+9[/tex]

Step-by-step 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 [tex](2x^2-8x+5)+(x^2+4)[/tex]. Then, to get the final answer remove the parentheses and add like terms. The terms [tex]2x^2[/tex] and [tex]x^2[/tex] are like while 5 and 4 are also like. If you add [tex]2x^2[/tex] and [tex]x^2[/tex] you get [tex]3x^2[/tex] and 5+4 is 9. Therefore, the final answer is [tex]3x^2-8x+9[/tex]
