The sum of the roots of $$x^2 - px + q = 0$$​ is ___________.

Correct option is C

Given:

Given equation = $$x^2 - px + q = 0$$​​

Formula Used:

If the roots of equation$$ax^2 +bx +c =0$$ are$$\alpha\ and\ \beta$$​​

Then sum of roots =$$\alpha + \beta= - \frac{b}{a}$$​​

Solution:

Given equation = $$x^2 - px + q = 0$$​​

Here a = 1 , b =-p and c = q

Sum of roots =$$- \frac{b}{a} = - \frac{-p}{1} = p$$​​
