campbell_st · Answer

so is the question 

$$y^3 + 72$$

since you are talking about sum and difference of cubes

taepoohwae · Answer

y^2+72

mertsj · Answer

It is NOT the sum of cubes because y^2 is not a cube and neither is 72

agent0smith · Answer

$$y^2+72 $$  you can only solve this if you use complex numbers, there are no real solutions. And as mertsj said, it is definitely not a sum or difference of cubes.
