Question

If x= -1/, is a solution of the quadratic equation 3x² +2kx -3 =0, find the value of k.
please answer ​

Answer 1

if x= -1

substitute in the quadratic equation

3(-1)²+2k(-1)-3=0

3-2kx-3=0

-2kx=0

therefore k=0

Answer 2

Answer:

0

Step-by-step explanation:

This question can be answered by putting the value of x in the equation, as it is its root. You can also solve it using the formula method.

1. Put the value of x = (-1) in the quadratic equation 3x² +2kx -3 = 0.
2. Calculate the answer through arithmetic operations, keeping k as it is.
3. Equate k to its value.
