Can anybody help... how is it possible to find the root of 16x^2-24x+k = 0 ? when one root is 1/2 and find k?

it is possible to find the value of k if the sum and product of the roots are equal?

if im going to solve i understand that in the k is the c part of quadratic equation.

so,

k = c/a = k/16 then in this part i am stuck.

it made me solve for hours but still can't get the answer correctly.

thank you so much and more power.
