Question 96327: If the two solutions of the qudratic equation 4x%5E2%2B4x%2Bk=0 are equal, find k.
I've completed the square to get %28x%2B1%2F2%29%5E2=%28-k%2F4%29%2B%281%2F4%29
I'm stuck on how to solve for k since the above equation when simplified is
x=sqrt%28%28-k%2F4%29%2B%281%2F4%29%29-%281%2F2%29
any assistance you can provide is greatly appreciated.
