Question

factorise using suitable identities :
a²+2+1/a²
plzzz give me the correct solution ​

Answer 1

Answer:

hope it helps, kindly mark me as brainliest :)

Step-by-step explanation:

a²+2+1/a²

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

using (a+b)^2 = a^2 + 2ab + b^2

= (a + $\frac{1}{a}$)^2

=(a + $\frac{1}{a}$)(a + $\frac{1}{a}$)

Answer 2

Step-by-step explanation:

a²+2+1/a²

=(a)²+2×a×1/a+(1/a)²

=(a+1/a)²

=(a+1/a) (a+1/a)
