Question 366738: I am doing quadratic equations, the problem is I understand most of it except for when I get to where the problem says x = -1 sqrt(47)/2 I don't know what to do with the square root symbol. I know how to find the vertex but I don't have the roots to graph the parabola, If some one could help me with this I would be grateful.

You can put this solution on YOUR website! You didn't show an equation. All equations have an equal sign.
If you mean you missed a sign somewhere, it's sqrt(49).
