Could someone explain how i can simplify this quadratic equation? I understand that you have to plug it into the quadratic formula. Then, you are to solve it. I did and got out 2 plus or minus the sqaure root of 425 all over 2, but I'm not fully clear on how to simplify this. Could someone please help me? I award medals :))) ;)))
