When Does A Quadratic Have One Solution? (3 Ways To Tell)

WebSo the solution is going to be negative b over 2a. And negative b is-- we could just solve it. Negative b is negative 14 over 2 times a. a is just 1 over 2. So it's equal to negative 7. That's the only solution to this equation. But if you just wanted to know how many solutions, you just have to find out that b squared minus 4ac is 0. http://academic.sun.ac.za/mathed/shoma/matunit14_02.htm period after quotation question mark
