    You need a common denominator 4x^2y and 3xy^3 would have a common denominator of 12x^2y^3 So that goes on the bottom of each fraction. To turn 4x^2y into 12x^2y^3 you would need to multiply by 3y^2 on top and bottom of the first fraction.. so the first fraction is 6xy^2 ------ 12x^2y^3

    On the second fraction... to turn 3xy^3 into 12x^2y^3 you would need to multiply the top and bottom of the second fraction by 4x so you would get 4x^2 ------- 12x^2y^3

    So now you have 6xy^2 4x^2 ------ + ---------- 12x^2y^3 12x^2y^3

    (6xy^2 + 4x^2) ------------- 12x^2y^3 but the top factors into 2x(3y^2 + 2x) ----------- 12x^2y^3 so the 12x cancels and you have 3y^2 + 2x --------- 6xy^3
