Помогите пожалуйста Найти производную функции функции y=xlnx/1-x^2

Решите задачу:

$\bf\displaystyle y=\frac{x\cdot ln(x)}{1-x^{2}}\\\\\\\\y' = \frac{(x\cdot ln(x))'(1-x^{2})-(x\cdot ln(x))(1-x^{2})'}{(1-x^{2})^{2}}\implies\\\\\frac{(x'\cdot ln(x) + x\cdot ln(x)')(1-x^{2}) - x\cdot ln(x)\cdot(-2x))}{(1-x^{2})^{2}}\implies\\\\\frac{(x\cdot ln(x) + x\cdot\frac{1}{x})(1-x^{2}) + 2x^{2}\cdot ln(x)}{(1-x^{2})^{2}}\implies\\\\\frac{(ln(x) + 1)(1-x^{2}) + 2x^{2}\cdot ln(x)}{(1-x^{2})^{2}}$
