expand (9(-e^2+1))/(10(e^2+9))+1

expand

\frac{9 ( - e ^{2} + 1 )}{10 ( e ^{2} + 9 )} + 1

\frac{- 9 e ^{2} + 9}{10 e ^{2} + 90} + 1

Decimal Notation

0.64914 \dots

Solution steps

\frac{9 ( - e ^{2} + 1 )}{10 ( e ^{2} + 9 )} + 1

\frac{9 ( - e ^{2} + 1 )}{10 ( e ^{2} + 9 )} = \frac{- 9 e ^{2} + 9}{10 e ^{2} + 90}

= \frac{- 9 e ^{2} + 9}{10 e ^{2} + 90} + 1

(t cos (t) + 2 sin (t))^{2}

\frac{x ^{2} - 9}{x ^{2} ( x + 4 )}

\frac{s ^{3} + 2 s + 6}{s ( s + 1 ) ^{2} ( s + 3 )}
