In the following question, two statements (i) and (ii) are given. Choose the valid statement. i. If $\alpha$ and $\beta$ are the roots of the equation ax2 + bx + c = 0, a $\neq$ 0 then $\alpha$ + $\beta$ = -b/a. ii. The equation ax2 + bx + c = 0 is quadratic for all real values of a, b, c.

Only (i) Explanation: Statement (i) is true because for the quadratic equation ax2 + bx + c = 0, a $\neq$ 0, the sum of the roots is given by alpha + beta = -b/a Statement (ii) is false because the equation is quadratic only when a $\neq$ 0. If a = 0, it becomes a linear equation.
