expand (12(1-cos(x)))/(x^2)

expand

\frac{12 ( 1 - cos ( x ) )}{x ^{2}}

\frac{12}{x ^{2}} - \frac{12 cos ( x )}{x ^{2}}

Solution steps

\frac{12 ( 1 - cos ( x ) )}{x ^{2}}

Expand

12 (1 - cos (x)) : 12 - 12 cos (x)

= \frac{12 - 12 cos ( x )}{x ^{2}}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{12 - 12 cos ( x )}{x ^{2}} = \frac{12}{x ^{2}} - \frac{12 cos ( x )}{x ^{2}}

= \frac{12}{x ^{2}} - \frac{12 cos ( x )}{x ^{2}}

u \cdot (1 - e^{- x})

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

- 2 + (- \frac{4}{3})

\frac{( x - 5 ) ( x + 2 )}{x ^{2} ( x - 4 )}

\frac{1}{( x - 8 ) ^{2}}
