Question

Find the sum of zeros of quadratic polynomial xsquare-9

Answer 1

$\textbf{Concept:}$

$\text{If \alpha and \beta are zeros of the polynomial}$

$\bf\;ax^2+bx+c,\;\text{then}$

$\bf\alpha+\beta=\frac{-b}{a}\;\text{and}\;\bf\alpha\;\beta=\frac{c}{a}$

$\text{Given polynomial is }x^2+0x-9$

$\text{Then,}$

$\text{Sum of the zeros =}\frac{0}{1}$

$\therefore\text{Sum of the zeros = 0}$
