Question

Expand using suitable identity (a+1upon2a)^2

Answer 1

Answer:

Using identity:-

$(a + b) {}^{2} = {a}^{2} + {b}^{2} + 2ab$

Step-by-step explanation:

We get,

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

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

Hope it helps.
