\[x^{2} + 3x - 2 -(2x ^{2} - x + 6)\]

Make sure the part being subtracted is in parentheses. Then distribute the negative.

OK, I thought maybe you'd distribute. So you'd distribute by adding x^2 to 2x^2?

Distribute by multiplying the -1 through the part you are subtracting.

\[(x ^{2}+3x+2)-(2x ^{2}-x+6 )= -x ^{2}+4x-4\]

Well it's a -2 - 6, so it becomes - 8 on the end.

You just had the sign of the 2 flipped :)
