Question

Please answer the above mentioned question

Answer 1

Hey

Here is your answer,

2(X^2 + 1)=5x
2x^2 + 2 -5x=0
2x^2-5x +2=0
2x^2 -4x -x +2=0
2x(x-2)-1(x-2)=0
(X-2)(2x-1)=0
X=1
X=1/2

(i) x-1/x

Substitute the value of x =1,

=1-1/1
=0

Substitute the value of x=1/2

=1/2 - 1/1/2
=1/2 -2
=1-4/2
=-3/2

Hope it helps you!
