If the sum of the zeros of the quadratic polynomial kx² − 3x + 5 is 1, write the value of k.

Open in App

Solution

By using the relationship between the zeros of the quadratic ploynomial.
We have
Sum of zeroes = $\frac{- (coefficient of x)}{coefficent of x^{2}}$
$\Rightarrow 1 = \frac{- (- 3)}{k} \Rightarrow k = 3$
