Find the sum.

(-3x^4 – 9x^3 - 4x^2 + 4) + (8x^3 – 7x^3 – x – 6)

o a.) -3x^4 + x^3 – 4x^2 – x – 2
o b.) 3x^4 + x^3 – 4x^2 – x – 2
o c.) -3x^4 – 8x^3 – 4x^2 – x – 2
o d.) 3x4^4 – x^3 – 4x^2 – x - 2

C.  

Step-by-step explanation:

-3x⁴ – 9x³ - 4x² + 0x + 4

          1x³  + 0x² – x – 6    

-3x⁴ - 8x³ - 4x² - x - 2
