When I use the roots to find the equation, I get x(x-20) giving me x^2-20x. However, this does not have a vertex of (10,10). Using vertex form, I can find y=-10x^2+200x-990 but this does not have roots of 0 and 20. After playing around on a graph, I found out that the graph is -1/10x^2+2x. However, how do I get to this equation. </SPAN>\n" );
