for subtracting this problem:

(0.04x^3-0.03x^2+0.02x)-(0.03x^3+0.08x^2-6)

I know to change the signs of the second grouping. When I done that, I cam up with:

0.04x^3-0.03x^2+0.02x-0.03x^3-0.08x^2+6 THEN

.01x^3 - .11x^2 + 0.02x + 6.....is that right??

the signs are changed b/c i had to find the opposite of each term.
