Answer: OPTION C

Step-by-step explanation:

To solve the exercise shown in the image attached, you need to subtract the functions f(x) and g(x).

Keeping the above on mind, you have:

$(f-g)(x)=2x^{2}+2-(x^{2}-1)$

You must distribute the negative sign and then you must add the like terms, therefore, you obtain:

$(f-g)(x)=2x^{2}+2-x^{2}+1\\(f-g)(x)=x^{2} +3$

Answer:

12a^2 - 9a + 5

Step-by-step explanation:

(5a^2 - 6a - 4) - (-7a^2 + 3a - 9)

5a^2 + 7a^2 = 12a^2

-6a - 3a = -9a

-4 + 9 = 5

12a^2 - 9a + 5
