How do you simplify this?

question: https://imgur.com/lK4IV1x

heyy, for this question I chose the 2nd option thinking that expanding that by getting the coefficients (is that the right term?) and putting them in brackets will simply allow me to expand that and give me the same equation.

I'm not too sure how else to solve this. I don't even know how the answers removed "x" without removing "y" whilst keeping the cube root. Can anyone help me out here please?
