----------------------------------
Divide 10^2 + 5x + 9 by 2x + 1
----------------------------------
(I assume you accidently omitted the "x" in the first term of the dividend so you want it as 10x^2+5x+9 ).

Using polynomial long division 5x 0x ___________________________ 2x+1 | 10x^2 +5x +9 10x^2 +5x ------------- 0 0x 9 0x 0 --------- 9
