HM between the roots of the equation

x^{2}-10 x+11=0

View answer and explanation

Correct option: D

\frac{11}{5}

Option D (

\frac{11}{5}

) is correct because the Harmonic Mean between the roots is calculated using the formula

\frac{2 \alpha \beta}{\alpha + \beta}

and substituting the values from the quadratic equation.
