Stop giving direct answers..

Answer 5

best thing is to organize terms of same order\[
\begin{array}
6x^3&+&0x^2&-&7x&-&4\\
4x^3&+&0x^2&+&8x&+&3\\
\hline
10x^3&+&0x^2&+&1x&-&1
\end{array}
\]

Answer 6

Thanks!

Answer 7

i added the 0x^2 because it is always better to lay our all the orders in a polynomial.

Answer 8

sorry @Luigi0210 I just suck at explaining. I"ll try to more often, though:)
