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

expand

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

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

Solution steps

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

(x - 1)^{2} = x^{2} - 2 x + 1

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

(\frac{1}{2} + \frac{1}{2} cos (2 x))^{4}

(x - x y) d y

e^{x} (x + 2)

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

(csc (θ) - 1) (sin (θ) + 1)
