$\"2sqrt%28x%2B4%29-1%2F2=x\"$
\n" ); document.write( " $\"sqrt%28x%2B4%29-1%2F2=x%2F2\"$
\n" ); document.write( " $\"sqrt%28x%2B4%29=x%2F2%2B1%2F2\"$
\n" ); document.write( " $\"x%2B4=%28x%2F2%2B1%2F2%29%5E2\"$
\n" ); document.write( " $\"x%2B4=x%5E2%2F4%2Bx%2F2%2B1%2F4\"$
\n" ); document.write( " $\"x%5E2%2F4%2Bx%2F2-15%2F4=0\"$
\n" ); document.write( "From here, the easiest method would be to use the quadratic equation:
\n" ); document.write( " $\"x=%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F%282a%29\"$
\n" ); document.write( "Your formula, $\"x%5E2%2F4%2Bx%2F2-15%2F4\"$ is in the form ax^2+bx+c.
\n" ); document.write( "So, a, b, and c are:
\n" ); document.write( " $\"a=1%2F4\"$
\n" ); document.write( " $\"b=1%2F2\"$
\n" ); document.write( " $\"c=-15%2F4\"$
\n" ); document.write( "From here, you just plug in a, b, and c into the quadratic formula.\r
\n" ); document.write( "\n" ); document.write( "I'll leave the rest to you.\r
