Answer:
= 1872x^2 - 1960q^2 - 1386xq
Step-by-step explanation:
First you should distribute.
(24x * 56q), (24x * 78x), (-35q * 56q), (-35q * 78x)
=1344xq + 1872x^2 - 1960q^2 - 2730xq
Now you combine like terms.
= 1872x^2 - 1960q^2 - 1386xq
**NOTE that (^2) means "squared"
Since there are no more like terms that is your final answer. I hope this helps love! :)
