Question

(a+1/a)^2
Write the formula

Answer 1

Step-by-step explanation:

it is in form of (a+b)^2

now(a+1/a)^2

=a^2 +1/a^2 +2(a×1/a)

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

a^2+1/a^2 +2 is answer

Answer 2

here we use the formula (a+b)^2

that is a^2+b^2+2ab

therefore (a+1/a)^2

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

=a is cancelled by a

therefore the answer will be

${a}^{2} + {b}^{2} + 2$
