Question

if a+1/a=2 find the value of a^2+1/a^2​

Answer 1

Answer:

2

Step-by-step explanation:

a+1/a=2

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

1+1/a=2

1/a=2-1

1/a=1

a=1

a^2+1/a^2=1^2+1/1^2=1+1/1=2/1=2

Answer 2

Answer:

2

Step-by-step explanation:

First we have to find the value of a.

1 (a+1 )=a X 2 [by cross multiplication]

a+1 = 2a

a -2a= -1

-a=-1

(-a) X(-1)=(-1) X (-1)

a = 1

ATQ 1 ² + 1/1² [ substituting 1 in the place of a ]

=2
