You can put this solution on YOUR website!
This is mostly just symbolic substitution and then simple algebraic steps.\r

\n" ); document.write( "\n" ); document.write( "Put the function into standard form using your given information.\r

\n" ); document.write( "\n" ); document.write( "\"highlight_green%28f%28x%29=a%28x-Vx%29%5E2%2BVy%29\", and as you, I am continuing to assume the lower case character in the mixed notation is like a subscript.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Wanting the roots, just equate f(x) to 0.
\n" ); document.write( "\"a%28x-Vx%29%5E2%2BVy=0\"
