Question

a^3 - 1/a^3 - 2a + 2/a​

Answer 1

Answer:

(a+1/a)(

Step-by-step explanation:

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

(a-1/a)(a^2+1/a^2+(a×1/a))-2(a-1/a)

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

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

Herr in step 3 a-1/a is common so we can factorise it

we can also keep a-1/a as x and after putting values answer will be same
