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

expand

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

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

Solution steps

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

Expand

(x + h)^{2} + 2 : x^{2} + 2 x h + h^{2} + 2

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

\frac{20}{s ( s + 12 ) + 4}

\frac{e ^{\frac{n ( n + 1 )}{2}}}{n}

f (5 a = 5 a - 2)

x (x^{3} - 9 x - 7 = 0)

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