If then that must mean is a root, so that you can factorise where the is some quadratic that you find by using long division on with . Then you can probably further factorise that quadratic.

By the way, post maths queries in the maths forum next time.

you need to do polynomial division
4. YouTube search algebraic long division for the second
once you use this you'll get a quadratic factor (I think that's it's name). Then you can factorise this to find all three overall linear factors.
Btw what were the ans to the Qs, wanna check with what I've done
