(a – b) (a2 + ab + b2) = …………… A) a3 – b B) a – b3

1.	(a – b) (a2 + ab + b2) = …………… A) a3 – b B) a – b3 C) a2 – b2D) None
Answer» Correct option is D) None Correct option is (D) None \((a–b)(a^2+ab+b^2)\) \(=a^3+a^2b+ab^2-a^2b-ab^2-b^3\) \(=a^3-b^3\)

(a – b) (a2 + ab + b2) = …………… A) a3 – b B) a – b3 C) a2 – b2D) None

Answer»

Correct option is D) None

Correct option is (D) None

\((a–b)(a^2+ab+b^2)\) \(=a^3+a^2b+ab^2-a^2b-ab^2-b^3\)

\(=a^3-b^3\)
