I'm really new to Algebra and I have been having a bit of trouble understanding why my answer to a question is wrong?
In a paper I'm told to expand $-3q(4q-8)+2q^2(q+1)$ my answer is $-10q^2+24q+2q^3$, but the actual answer is $2q^3-10q^2+24q$.
Can someone please explain why my answer is slightly wrong. It looks like the actual answer has the terms arranged from smallest number to largest. A working out showing how I can get the answer would be really appreciated. Thanks.
actually we get by expanding $$-12q^2+24q+2q^3+2q^2=-10q^2+24q+2q^3$$ your answer is right!
