Sum of roots of quadratic equation px² - qx + r = 0 is _____?
- q/p
- p/q
- r/p
- None of these
Explanation
For a quadratic equation in the form of ax² + bx + c = 0, the sum of the roots is given by -b/a.
Given the equation px² - qx + r = 0:
Step 1: Identify a and b
a = p, b = -q
Step 2: Calculate the sum of roots
Sum of roots = -(-q) / p
= q / p
