expand (xy(y+2)(y-2))/(y+6)

expand

\frac{x y ( y + 2 ) ( y - 2 )}{y + 6}

\frac{x y ^{3} - 4 x y}{y + 6}

Solution steps

\frac{x y ( y + 2 ) ( y - 2 )}{y + 6}

Expand

x y (y + 2) (y - 2) : x y^{3} - 4 x y

= \frac{x y ^{3} - 4 x y}{y + 6}

6 a \cdot (5 - 3)

\frac{x ( x + 1 )}{x - 1}

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

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

tan (\frac{β}{2}) \cdot (1 + cos (β))
