And no I do not mean these expressions :) :( :!
I mean Functions.
For example if the roots given are (x-3) and (x+6) then you can use F.O.I.L (First, Outer, Inner, Last).
So this is how it would look:
So x*x=X^2
-3*6=-18
6*x=6x
-3*x=-3x
NOW COMBINE LIKE TERMS:
-3x+6x=3x
Full equation would then be X^2+3x-18
