Question

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

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

You just had the sign of the 2 flipped :)

Answer 8

ohh yeah..sry ...
