You can put this solution on YOUR website!
$\"+y+=+x%5E3+-+2x%5E2+%2B+x+-+1+\"$
\n" ); document.write( " $\"+y+=+-x%5E2+%2B+3x+-+1+\"$
\n" ); document.write( "By substitution:
\n" ); document.write( " $\"+x%5E3+-+2x%5E2+%2B+x+-+1+=+-x%5E2+%2B+3x+-+1+\"$
\n" ); document.write( "Add $\"1\"$ to both sides
\n" ); document.write( " $\"+x%5E3+-+2x%5E2+%2B+x++=+-x%5E2+%2B+3x++\"$
\n" ); document.write( " $\"+x%5E3+-+x%5E2+-+2x+=+0+\"$
\n" ); document.write( "Factor out $\"+x+\"$
\n" ); document.write( " $\"+x%2A%28+x%5E2+-+x+-+2+%29+\"$
\n" ); document.write( "The solutions are:
\n" ); document.write( " $\"+x+=+0+\"$
\n" ); document.write( " $\"+x%5E2+-+x+-+2+=+0+\"$
\n" ); document.write( " $\"+%28+x+-+2+%29%2A%28+x+%2B+1+%29+=+0+\"$
\n" ); document.write( " $\"+x+=+2+\"$
\n" ); document.write( " $\"+x+=+-1+\"$
\n" ); document.write( "You can verify these by plugging them
\n" ); document.write( "back into $\"+x%5E3+-+x%5E2+-+2x+=+0+\"$ \r
