You can put this solution on YOUR website!
All three of these equations:
\n" ); document.write( "Equation 1: $\"+%285%2F2%29y=x%5E2+\"$
\n" ); document.write( "Equation 2: $\"+x%5E2=%285%2F2%29y+\"$
\n" ); document.write( "Equation 3: $\"+-x%5E2=-%285%2F2%29y\"$
\n" ); document.write( "mean the same thing.
\n" ); document.write( "Look at equation 3:
\n" ); document.write( " $\"+-x%5E2=-%285%2F2%29y\"$
\n" ); document.write( "If you divide both sides by -1, you end up with:
\n" ); document.write( " $\"x%5E2=%285%2F2%29y\"$
\n" ); document.write( "This is the same equation as equation 2!
\n" ); document.write( "Essentially, what this means is that you can re-order the equation in either way that you like. They both mean the same thing.
\n" ); document.write( "Hope this helps! \n" ); document.write( "
