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

expand

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

\frac{1 - x}{4 - 4 x + x ^{2}}

Solution steps

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

(2 - x)^{2} = 4 - 4 x + x^{2}

= \frac{1 - x}{4 - 4 x + x ^{2}}

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

a cos (ω t - k x) + a cos (ω t - k (x + δ x))

e (\frac{- π + 1 + π ^{2}}{π ^{2} - π} - 1)

\frac{k ( s + 1 )}{s ^{2} ( s + 10 ) ( s + 100 )}

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