Answer 1

Value of $k$ is $\dfrac{15}{4}$

Explanation:

Given equation: $3x^{2}+2kx+3=0$

Since $x=-\dfrac{1}{2}$ is one of its roots, then it satisfies the above equation

$\Rightarrow 3(-\dfrac{1}{2})^{2}+2k(-\dfrac{1}{2})+3=0$

$\Rightarrow \dfrac{3}{4}-k+3=0$

$\Rightarrow k=\dfrac{3}{4}+3$

$\Rightarrow k=\dfrac{3+3\times 4}{4}$

$\Rightarrow k=\dfrac{3+12}{4}$

$\Rightarrow k=\dfrac{15}{4}$
