Answer 2

Answer:

Hiii,

Hiii,a + 1/a = 3

Hiii,a + 1/a = 3=>(a + 1/a)^ = 3^2

Hiii,a + 1/a = 3=>(a + 1/a)^ = 3^2=>a^2 + 2. a. 1/a + 1/a^2 = 9

Hiii,a + 1/a = 3=>(a + 1/a)^ = 3^2=>a^2 + 2. a. 1/a + 1/a^2 = 9=>a^2 + 2 + 1/a^2 = 9

Hiii,a + 1/a = 3=>(a + 1/a)^ = 3^2=>a^2 + 2. a. 1/a + 1/a^2 = 9=>a^2 + 2 + 1/a^2 = 9=> a^2 + 1/a^2 = 9-2 = 7

hope it will help you.......❣️
