expand (1+x^2)/(x^2(s-3)^2)

expand

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

\frac{1 + x ^{2}}{x ^{2} s ^{2} - 6 x ^{2} s + 9 x ^{2}}

Solution steps

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

(s - 3)^{2} = s^{2} - 6 s + 9

= \frac{1 + x ^{2}}{x ^{2} ( s ^{2} - 6 s + 9 )}

Expand

x^{2} (s^{2} - 6 s + 9) : x^{2} s^{2} - 6 x^{2} s + 9 x^{2}

= \frac{1 + x ^{2}}{x ^{2} s ^{2} - 6 x ^{2} s + 9 x ^{2}}

\frac{e ^{x} ( 1 - sin ( x ) )}{( 1 - cos ( x ) )}

e^{t^{2}} \cdot (4 t^{3} - 7 t^{2} + 9 t)

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

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

(e^{x} + 4)^{2}
