Did you post that correctly??
You can put this solution on YOUR website! It is strange to have on both sides of the equal sign.
If you did post correctly, <--><-->
If the graph of that quadratic function crosses the ,
meaning that will give two distinct solutions for .
That means has two distinct solutions for .
If a quadratic equation has two distinct solutions for ,
it means that the discriminant is positive: .
In this case, that would be
