Homework Help: ALGEBRA

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.
