Factor this expression completely, then place the factors in the proper location on the grid. x^3 + y^3
\[x^3+y^3=(x+y)(x^2-xy+y^2)\] (you have to memorize this)
If you really want to know how this can be done, try expanding the right hand side and see if you get the left hand side
(x-y)(x^2+xy+y^2) this a^3+b^3 formula
I've tried that and I keep only getting half credit. @HARSH123

so u want me to solve the eq or the formulae
Help me solve the equation by using the formula
it's derivation is too long so u can simply write the formulae and then ur eq this is quite enough
Well because I got (x-y) (x^2+xy+y^2) and apparently only some of that is right.
