Q1. If m and n are the roots of the equation x^2 + px + q = 0, then what is m^2 + n^2 equal to?

A p^2 + 2q

B p^2 + q

C p^2 - 2q Correct

D p^2 - q

Explanation

For the quadratic equation x^2 + px + q = 0, the sum of the roots is m + n = -p and the product is mn = q. Now m^2 + n^2 = (m + n)^2 - 2mn. Substituting these values gives (-p)^2 - 2q, which simplifies to p^2 - 2q. Expressions with +2q, +q, or -q do not follow from subtracting twice the product of the roots, so they are not correct.
