Question

Find the sum and product of zeros of quadratic polynomial $3x^2-4x+7$.

Answer 1

Sum and product of a quadratic polynomial $a{x}^2+bx+c$ is given by $\frac{-b}{a},\frac{c}{a}$ respectively.

Given polynomial $3x^2-4x+7$

sum of roots = $\frac{-(-4)}{3}=\frac{4}{3}$

Product of roots = $\frac{7}{3}$
