A teacher gave a question to find the roots of the equation

{(x)/(x+1)} + {(x+1)/x;. Ravi and Ankit cheated from each other but

Sahil solved it of his own, Ravi said one of the roots is 3/2. Ankit said one

of the roots is -5/2. Sahil said this is not possible to find as the discriminant

is negative. Who’s answer is correct and what moral value you get from it?

Given :A teacher gave a question to find the roots of the equationRavi said one of the roots is 3/2. Ankit said one of the roots is -5/2.

Sahil said this is not possible to find as the discriminant is negative.

To Find :Who is correctSolution:x/(x +1 ) + (x + 1)/x = 0

=> x² + (x + 1)² = 0

=> x² + x² + 2x + 1 = 0

=> 2x² + 2x + 1 = 0

D = 2² – 4(2)(1)

=> D = 4 – 8

=> D = – 4

D < 0

discriminant is negative

Roots are not real

Hence Sahil is correct that

this is not possible to find as the discriminant is negative

SAHIL is correct
