Do you mean
\n" ); document.write( " $\"+P%28x%29+=+2x%5E4+%2B+x%5E3+%2B+12+\"$ \r
\n" ); document.write( "\n" ); document.write( "If so, the question is a straightforward exercise in evaluating functions.
\n" ); document.write( " $\"+P%28-1%2F2%29+=+2%28-1%2F2%29%5E4+%2B+%28-1%2F2%29%5E3+%2B+12+\"$
\n" ); document.write( "What I have done is to replace every instance of x with (-1/2)
\n" ); document.write( "This gives
\n" ); document.write( "2(-1/2)^4 + (-1/2)^3 + 12
\n" ); document.write( "= 2(1/16) + (-1/8) + 12
\n" ); document.write( "= 1/8 - 1/8 + 12
\n" ); document.write( "= 12\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
