expand (3(x^2-16))/(2x+4)

expand

\frac{3 ( x ^{2} - 16 )}{2 x + 4}

\frac{3 x ^{2} - 48}{2 x + 4}

Solution steps

\frac{3 ( x ^{2} - 16 )}{2 x + 4}

Expand

3 (x^{2} - 16) : 3 x^{2} - 48

= \frac{3 x ^{2} - 48}{2 x + 4}

\frac{x ( 25 - 4 x ^{2} - 4 y ^{2} )}{y ( 4 x ^{2} + 4 y ^{2} + 25 )}

(x - 5 i)^{2}

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

\frac{( tan ( x ) + sin ( x ) ) cos ( x )}{csc ( x ) + cot ( x )}

\frac{n !}{n ( n - 1 )}
