Given that the sum of the zeros of the polynomial kx2 - 3x + 5 is 1, we have to find the value of k.
We have, f(x) = kx2 - 3x + 5
Sum of zeros = {tex}\frac { - \left( \text { coefficient of } x ^ { 2 } \right) } { \text { coefficient of } x } = \frac { - ( - 3 ) } { k } = \frac { 3 } { k }{/tex}
Given, sum of zeros = 1
{tex}\therefore \frac{3}{k}{/tex} = 1
{tex}\Rightarrow{/tex} k = 3
