How do you factor #x^3 + (x + y)^3#? Algebra Polynomials and Factoring Factor Polynomials Using Special Products 1 Answer Shwetank Mauria Jan 18, 2017 #x^3+(x+y)^3=(2x+y)(x^2+xy+y^2)# Explanation: Here, we can use the identity #a^3+b^3=(a+b)(a^2-ab+b^2)# Hence #x^3+(x+y)^3# = #(x+(x+y))(x^2-x(x+y)+(x+y)^2)# = #(2x+y)(x^2-x^2-xy+x^2+2xy+y^2)# = #(2x+y)(x^2+xy+y^2)# Answer link Related questions How do you factor special products of polynomials?
