You can put this solution on YOUR website!
As a general model, you can do this from the equation using all variables, and then use the resulting formula result.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "First, adjust the equation as given.
\n" ); document.write( "\"5x%5E2%2B30x-51=-24y\"
\n" ); document.write( "\"24y=-5x%5E2-30x%2B51\"
\n" ); document.write( "\"y=-%285%2F24%29x%5E2-%2830%2F24%29x%2B51%2F24\"
\n" ); document.write( "\"y=-%285%2F24%29x%5E2-%285%2F4%29x%2B17%2F8\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now is a good place to examine the rest all in symbols to get a formula.
\n" ); document.write( "\"system%28a=-5%2F24%2Cb=-5%2F4%2Cc=17%2F8%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=ax%5E2%2Bbx%2Bc\"\r
\n" ); document.write( "\n" ); document.write( "Continue by using Completing The Square.
\n" ); document.write( "\"y=a%28x%5E2%2B%28b%2Fa%29x%2Bc%2Fa%29\"
\n" ); document.write( "\"y=a%28x%5E2%2B%28b%2Fa%29x%2B%28b%2F%282a%29%29%5E2-%28b%2F%282a%29%29%5E2%2Bc%2Fa%29\"
\n" ); document.write( "Watch and check through the next step carefully...
\n" ); document.write( "\"y=a%28%28x%2B%28b%2F%282a%29%29%29%5E2%2Bc%2Fa-%28b%5E2%29%2F%284a%5E2%29%29\"
\n" ); document.write( "Now distribute the factor, \"a\"...
\n" ); document.write( "\"y=a%28x%2B%28b%2F%282a%29%29%29%5E2%2Bc-%28b%5E2%29%2F%284a%29\"-----which may be useful enough this way or you could keep going like this....\r

\n" ); document.write( "\n" ); document.write( "Note also, if you understand the process just shown, you could do the same thing starting from \"y=-%285%2F24%29x%5E2-%285%2F4%29x%2B17%2F8\". I would not want to using your example; I would prefer to find a formula and then plug the values I need..... and then simplify as a last set of steps.
