Solve:
\n" ); document.write( " $\"3+=+%285%2Fx%29%2B%284%2Fx%5E2%29\"$ Multiply through by $\"x%5E2\"$
\n" ); document.write( " $\"3x%5E2+=+5x%2B4\"$ Rewrite as:
\n" ); document.write( " $\"3x%5E2-5x-4+=+0\"$ Solve with the quadratic formula: $\"x+=+%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F2a\"$ and here, a = 3, b = -5, and c = -4.
\n" ); document.write( " $\"x+=+%28-%28-5%29%2B-sqrt%28%28-5%29%5E2-4%283%29%28-4%29%29%29%2F2%283%29\"$ Do the math.
\n" ); document.write( " $\"x+=+%285%2B-sqrt%2825%2B48%29%29%2F6\"$
\n" ); document.write( " $\"x+=+%285%2B-sqrt%2873%29%29%2F6\"$
\n" ); document.write( " \n" ); document.write( "
