I'm having trouble working out these problems. Could someone please assist?

Question

with this first one do I factor the x^2 + 3xy - 18y^2 first?

x - 3y * x^2 + xy - 30y^2 /
x^2 + 3xy - 18y^2

3a^3b^2 * 4a^2 + 2ab + b^2
8a^3 - b^3 12ab^4

3y + 12 / 9y+36
8y^3 16y^3

Susan I see these are rational fractions. I'm not sure though, do you mean for them to be poly's like p(x)/q(x)?
If they are, then factor them to find common terms. Are you sure the numerator of the first one is written correctly? You can factor in either order, but keep track of numerator and denominator factors. Cancel common ones.
