Question

expand the following Identities-

a³+ b³

a³- b³

a⁴-b⁴

Answer 1

hey friend☺️

the answers are given below:-

a.a^3+b^3
(a+b)^3-3ab(a+b)

b.a^3-b^3
(a-b)^3+3ab(a-b)


c.a^4-b^4
(a2-b2)^2-2a^2b^2

thank you❤️

Answer 2

 · a³ + b³ = (a + b)(a² – ab + b²) ... then a³ + b³ = (a + b)³ – 3ab(a + b)

a³-b³=(a-b)(a²+ab+b²) ... What is the formula of a3+b3a^3+b^3 ? ... Formula for a3-b3 is (a-b) (a2+ab+b2).
