You can put this solution on YOUR website!
A) 3
\n" ); document.write( "Let $\"+x+=+0+\"$
\n" ); document.write( " $\"+%28+x-1+%29%5E4+=+1+\"$
\n" ); document.write( " $\"+%28+0-1+%29%5E4+=+1+\"$
\n" ); document.write( " $\"+-1+\"$ raised to an even power = $\"+1+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+x+%2B+3+=+0+%2B+3+\"$
\n" ); document.write( "-------------------------
\n" ); document.write( "The other solution is:
\n" ); document.write( " $\"+%28+2+-+1+%29%5E4+=+1+\"$
\n" ); document.write( " $\"+1%5E4+=+1+\"$
\n" ); document.write( "but
\n" ); document.write( " $\"+2+%2B+3+=+5+\"$ which is not one of the choices
\n" ); document.write( " \n" ); document.write( "

\n" );
