# If x=−1/2, is a solution of the quadratic equation 3x^2+2kx−3=0, find the value of k - Mathematics

Sum

If x=1/2, is a solution of the quadratic equation 3x2+2kx3=0, find the value of k

#### Solution

It is given that x=1/2 is the solution of the quadratic equation 3x2+2kx3=0

:.3(-1/2)^2+2k(-1/2)-3=0

=>3/4-k-3=0

=>k=3/4-3=-9/4

Hence, the value of k is -9/4
