We do it the same way. Let me work for a second here...

\[2C + 3B +6Cx+2A+2Bx+2Cx^2=12x^2 \implies\]\[(2A+2C + 3B) +(6C+2B)x+2Cx^2=12x^2 \implies\]\[2C=12 \implies C=6\]\[6C+2B=0 \implies B=18\]\[2A+2C + 3B=0 \implies A=9\]

The corresponding terms on the left and right sides of the equation have to be the same. So, we match the x^2 coefficients to get C=6, then the x coefficients (note there is none on the RHS, so the LHS has to be zero) to get B=18, then follow the same pattern to get A=9.

I think it's nine.... 3*62*18=18 implies that A has to be pretty close to nine.
