So 4/(x+2) = ?/((x+2)(x+1))
Do the cross multiplying thing:
4(x+2)(x+1) = ?*(x+2)
Divide both sides by (x+2) and distribute:
4x+8 = ?
so 4x+8 is the answer.

4 / (x + 2) = [4 (x + 1)] / [ (x + 2) (x + 1) ]
? = 4 (x + 1)

4/(x+2) = ?/[(x+2)(x+1)]
cross multiply
4*(x+2)(x+1) = ?*(x+2)
divide by (x+2)
4*(x+1) = ?

I don't get it but I will give it a try.
I think what you are trying to say is that you need a quadratic equation that is equivalent to (X+2)(X+1)
You do the *FOIL method and combine the similar terms
*FOIL - Multiplying the First part, the outer part, inner part and last part.
Thus the answer would be x(squared)+3X+y(squared).
