y=%284ln%28x%2B3%29%29%2Fx%5E2
==> y' = %28x%5E2%2A4%2A%281%2F%28x%2B3%29%29+-+4%2Aln%28x%2B3%29%2A2x%29%2Fx%5E4, by direct application of the quotient rule.
==> y' = %28%284x%5E2%29%2F%28x%2B3%29+-+8xln%28x%2B3%29%29%2Fx%5E4
==> y' = %28%284x%29%2F%28x%2B3%29+-+8ln%28x%2B3%29%29%2Fx%5E3
==> y' = %284x+-+8%28x%2B3%29ln%28x%2B3%29%29%2F%28x%5E3%28x%2B3%29%29
