expand (-xy'(x)+y)+(xy'(x)-y)y

expand

(- x y^{'} (x) + y) + (x y^{'} (x) - y) y

- x y' (x) + y + x yy' (x) - y^{2}

Solution steps

(- x y^{'} (x) + y) + (x y^{'} (x) - y) y

Expand

y (x y^{'} (x) - y) : x y y^{'} (x) - y^{2}

= (- x y^{'} (x) + y) + x y y^{'} (x) - y^{2}

Remove parentheses:

(- a) = - a

= - x y^{^{'}} (x) + y + x y y^{^{'}} (x) - y^{2}

\frac{1}{( t ^{2} + 1 ) ^{2}}
