To make $\"x%5E2%2B3x\"$ into a perfect square trinomial, you need to add the square of half the coefficient of x. The coefficient of x is 3, so the square of half that is $\"%283%2F2%29%5E2+=+9%2F4\"$ \r
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( " $\"x%5E2+%2B+3x+%2B+9%2F4+=+%28x+%2B+3%2F2%29%28x+%2B+3%2F2%29\"$ = $\"%28x+%2B+3%2F2%29%5E2\"$ \n" ); document.write( "

\n" );
