If roots of the quadratic equation $a x^2+b x+c=0$ are reciprocal to each other then coefficient of $x^2$ and constant term are……………. (unequal, equal, actuated)
If the equation $a x^2+b x+c=0$ has two real and equal roots then the sum of the roots is......... $\left(\frac{+b}{a}, \frac{-b}{a}, \frac{a}{b}\right)$
The value of $x$ which satisfy the quadratic equation $a x^2+b x+c=0$ $a x^2+b x+c=0(a \neq 0)$ are called…………. (constant, variable, roots or solution)
