simplify (1-1/b)(mr^2-I)

simplify

(1 - \frac{1}{b}) (m r^{2} - I)

\frac{( b - 1 ) ( m r ^{2} - I )}{b}

Solution steps

(1 - \frac{1}{b}) (m r^{2} - I)

Join

1 - \frac{1}{b} : \frac{b - 1}{b}

= \frac{b - 1}{b} (m r^{2} - I)

Apply the fraction rule:

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

= \frac{( b - 1 ) ( m r ^{2} - I )}{b}

\frac{( - x ^{2} - 9 )}{( x ^{2} - 9 ) ^{2}}

\frac{1 - e ^{- 2 s}}{s ( s ^{2} + 5 s + 4 )}

\frac{( s + 3 ) ( s + 5 )}{s ( s + 2 ) ( s + 4 )}

\frac{12 x ( - 2 x ^{3} + 1 )}{( x ^{3} + 1 ) ^{3}}

(3 - 4 - x)^{2}
