You can put this solution on YOUR website!
Not sure why you want to complete the square to find the inverse.

\n" ); document.write( "\n" ); document.write( "You won't find a closed form solution for this inverse.
\n" ); document.write( "Typically you interchange the x and y variables and solve for y.
\n" ); document.write( "The new y is the inverse.
\n" ); document.write( " $\"y=3x%2B7x%5E17\"$
\n" ); document.write( "So then it would be,
\n" ); document.write( " $\"x=3y%2B7y%5E17\"$
\n" ); document.write( "But isolating y in this equation is not possible.
\n" ); document.write( "You'd have to use numerical methods to get a handle on the inverse.
