Answer 2

The value of $k=\frac{7}{4}$.

Step-by-step explanation:

Given : Equation $kx^2-2x-3=0$

To find : The value of k for which X equal to 2 is the solution of the equation ?

Solution :

If x=2 is the root of the equation then it satisfy the equation.

Equation  $kx^2-2x-3=0$

Substitute x=2 in the equation,

$k(2)^2-2(2)-3=0$

$4k-4-3=0$

$4k-7=0$

$4k=7$

$k=\frac{7}{4}$

Therefore, the value of $k=\frac{7}{4}$.
