I need someone to solve these problems. If you know how to solve a quadratic equation please help me. I don't know how to solve quadratic equations but, I do know that they are not suppose to be factored. If you do not know what I'm talking about please do not post....because most likely you will just factor the problem out. Thanks!
1. x^2 - 4x - 5 = 0
2. z^2 - 2z - 15 = 0
3. y^2 = 2y + 3
4. r^2 = 5 - 4r
Once again, thanks for the help!
