The number of real solutions of the equation 3x2+1x2−2x+1x+5=0 is

3[(x2+1x2)−2(x+1x)+5=0 Put x+1x=t,x2+1x2=t2-2 3t2−2t−1=0 t=1,−13x+1x=1,x+1x=−13∴No real solution

Detailed Solution

$3 [(x^{2} + \frac{1}{x^{2}}) - 2 (x + \frac{1}{x}) + 5 = 0 Put x + \frac{1}{x} = t, x^{2} + \frac{1}{x^{2}} = t^{2} - 2$

$3 t^{2} - 2 t - 1 = 0 t = 1, \frac{- 1}{3}$

$x + \frac{1}{x} = 1, x + \frac{1}{x} = - \frac{1}{3} ∴ No real solution$
