Hi all! Just need help with this problem

 

Anjelica is using synthetic division to divide  2x3−9x2−21x+10  by  x+2 .

 

Which answer is correct?

Please and thank you! 0^>

We can easily eliminate (B) and (D), for not having -9 for one of the coefficients. Since it has to be -2 instead of 2, the only answer is (C), the third option.
