Question

factorise :125x^3+8y^3+z^3-30xyz​

Answer 1

Step-by-step explanation:

125x^3 + 8y^3 + z^3 -30xyz

= (5x)^3 + (2y)^3 + z^3 -3×5x×2y×z

=(5x +2y +z)(25x^2 +4y^2 +z^2 -10xy-2yz-5xz)

Answer 2

Step-by-step explanation:

125x^3 + 8y^3 + z^3 -30xyz

(5x)^3 + (2y)^3 + z^3 -3x5x×2yxz

=(5x +2y +z)(25x^2 +4y^2 +z^2

-10xy-2yz-5xz)
