Solution - Verify :- x^3 – y^3 = (x – y) (x^2 + xy + y^2) - CBSE Class 9 - Mathematics

Question

Verify :- x3 – y3 = (x – y) (x2 + xy + y2)

Solution

x3 – y3 (– y)(x2 xy2)

Wknothat,

(– y)3 x3 – y3 – 3xy(– y)

⇒ x3 − y3 (– y)3 3xy(– y)

⇒ x3 − y3 (– y)[(– y)2 3xy]                              Takin(x - y)common

⇒ x3 − y3 (– y)[(x2 y2 – 2xy3xy]

⇒ x3 y3 (– y)(x2 y2 xy)

  Is there an error in this question or solution?
