expand 2(x-y)(1-(dy)/(dx))

expand

2 (x - y) (1 - \frac{d y}{d x})

2 x - 2 x \frac{d y}{d x} - 2 y + 2 y \frac{d y}{d x}

Solution steps

2 (x - y) (1 - \frac{d y}{d x})

Expand

(x - y) (1 - \frac{d y}{d x}) : x - x \frac{d y}{d x} - y + y \frac{d y}{d x}

= 2 (x - x \frac{d y}{d x} - y + y \frac{d y}{d x})

Expand

2 (x - x \frac{d y}{d x} - y + y \frac{d y}{d x}) : 2 x - 2 x \frac{d y}{d x} - 2 y + 2 y \frac{d y}{d x}

= 2 x - 2 x \frac{d y}{d x} - 2 y + 2 y \frac{d y}{d x}

\frac{x}{( 1 + 3 x ^{2} ) ^{2}}

\frac{( x + 1 ) ^{4}}{4}

lo g_{2} (4 w z)

\frac{x ^{4} - x ^{3} - 9 x ^{2} - 9 x - 27}{x ^{3} ( x + 3 ) ( x - 3 )}

\frac{x ^{2} - 3}{( s + 2 ) ( x ^{2} + 2 x + 1 )}
