Question 70362: [(7x^2-9x+4)-(9x^2+3x-2)]-[(5x^2+4x-6)+(-8x^2+6x+1)]

Ok I can get all the way to the end and then I'm stuck.
Below is what I ended up with:
= -9x^2+8x^2+7x^2-5x^2-9x-6x-4x-3x+4+2+6-1
= x^2-4x+11 (<---is that right)

Below is what I ended up with:
.
= -9x^2+8x^2+7x^2-5x^2-9x-6x-4x-3x+4+2+6-1 <----This is correct!
.
= x^2-4x+11 (<---is that right. No it's not. Look at -4x. How did you get the -4? The x^2 and
the +11 are OK.)
.
You obviously know how to work these, but just made a minor mistake. Keep up the good work!
