Answer:

the answer of this question will be like this ...

Answer 2

Answer:

a^3-1/a^3-2a+2/a

=(a)^3-(1/a)^3-2(a-1/a)

=(a-1/a)^3+3.a.1/a(a-1/a)-2(a-1/a)

=(a-1/a)^3+3(a-1/a)-2(a-1/a)

=(a-1/a)^3+(a-1/a)

=(a-1/a){(a-1/a)^2+1}

=(a-1/a)(a^2+1/a^2-2.a.1/a+1)

=(a-1/a)(a^2+1/a^2-2+1)

=(a-1/a)(a^2+1/a^2-1)
