x^3+y^3=(x+y)^{3}-3xy(x+y)

x^3+y^3=(x+y)(x+y)(x^{2} -xy+y^{2} )

Step-by-step explanation:

We have,

x^3+y^3

To find, all formulas of x^3+y^3=?

We know that,

(x+y)^{3}=x^{3} +y^{3} +3x^{2} y+3xy^{2} =x^{3} +y^{3}+3xy(x+y)

x^{3} +y^{3}=(x+y)^{3}-3xy(x+y)

Also,

x^3+y^3=(x+y)^3-3xy(x+y)

All formulas of x^3+y^3=(x+y)^{3}-3xy(x+y)

x^3+y^3=(x+y)(x+y)(x^{2} -xy+y^{2} )

Hence, x^3+y^3=(x+y)^{3}-3xy(x+y)

x^3+y^3=(x+y)(x+y)(x^{2} -xy+y^{2} )
