We have the following question:
\n" ); document.write( " $\"4x%5E2=18\"$
\n" ); document.write( "In this case, you do not have to set = 0.
\n" ); document.write( "step 1 - divide both sides by 4 to get
\n" ); document.write( " $\"x%5E2+=+18%2F4\"$
\n" ); document.write( "step 2 - take sqrt of both sides to get
\n" ); document.write( " $\"x+=+sqrt%2818%29+%2F+2\"$ or $\"x+=+-sqrt%2818%29+%2F+2\"$
\n" ); document.write( "which simplifies to
\n" ); document.write( " $\"x+=+%2B3sqrt%282%29+%2F+2\"$ or $\"x+=+-3sqrt%282%29+%2F+2\"$ \n" ); document.write( "

\n" );
