If 2x^2 - x + 6 is subtracted from x^2 + 3x-2, what is the answer? (Any ideas on where to start, operations wise?)

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

    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 :)
