Question

If x= (-12 ), is a solution of the quadratic equation 3x2+2kx-3=0, find the value of k​

Answer 1

Answer:

I don't know these types of equation

Answer 2

Answer: k = -75/24

Step-by-step explanation: 3x2 + 2kx - 3 = 0

Substituting x = -12 in the equation

 6*-12 + 2*-12*k - 3 = 0

-72-3 + (-24k) = 0

-75 + (-24k) = 0

taking -75 on the other side

-24k = 75

k = 75/-24

k = -75/24
