expand (s^2-r^2)/((t-s)^2)

expand

\frac{s ^{2} - r ^{2}}{( t - s ) ^{2}}

\frac{s ^{2} - r ^{2}}{t ^{2} - 2 s t + s ^{2}}

Solution steps

\frac{s ^{2} - r ^{2}}{( t - s ) ^{2}}

(t - s)^{2} = t^{2} - 2 s t + s^{2}

= \frac{s ^{2} - r ^{2}}{t ^{2} - 2 s t + s ^{2}}

\frac{( n ^{2} - 4 ) ^{2}}{4 n ^{2}}

y (x + 1) d x - 5 d x

\frac{9 s - 31}{( s - 3 ) ( s - 4 )}

t (2 t, - 5, t^{2})

\frac{x ^{2} + 3 x - 16}{( x + 7 ) ( x + 5 )}
