Question

If x-1/x=2then the value of x²+1/x²

Answer 1

Answer: x-1/x=2

(x-1/x)^2= 2^2

x^2+(1/x)^2 - 2x*1/x = 4

x^2+(1/x)^2 = 4+2

x^2+(1/x)^2 = 6

Answer 2

x-1/x=2

So , x-1=2x

So, x-1-2x=0

So, -x-1=0

So, x=-1.

Value of x²+1/x² is = [(-1)^2+1]÷(-1)

=[1+1]÷(-1)

=2/-1

=-2.

So , -2 is the value of x²+1/x² .
