Question

if the sum of the zeros of the polynomial 2x²-3kx²+4x-5 is 6 then value of k is​

Answer 1

Given:-

$\text { The sum of the zeroes of the equation } a x^{3}+b x^{2}+c x+d \text { is }-b / a\\\text { Here the equation is } 2 \mathrm{x}^{3}-3 \mathrm{kx}^{2}+4 \mathrm{x}-5\\\\\begin{array}{l}\Rightarrow \text { Sum of roots }=3 \mathrm{k} / 2 \\\Rightarrow 3 \mathrm{k} / 2=6 \\\Rightarrow \mathrm{k}=4\end{array}$
