Answer 1

do u undestand

Answer 2

pretty much, just figuring out a couple of stuff

Answer 3

you know what, i'm not going to waste loads of time with formulas. I'm not an expert but i'll tell you the obvious. find the the first 3 terms(a,b,c) of the product (ef) in acending powers.

Answer 4

simple mutiplication.... \[= 1(4+x ^{2}-2x ^{4}) - 2x ^{2}(4+x ^{2}-2x ^{4})-x ^{4}(4+x ^{2}-2x ^{4})\]
\[=4+x ^{2}-2x ^{4}\] ^^^^^^^^^^^ First 3 terms

Answer 5

ok thanks

Answer 6

I'm not too sure but its just what i think out of the obvious
