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

expand

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

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

Solution steps

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

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

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

\frac{( x + 3 ) ^{3}}{( x + 2 ) ^{2}}

(x + Δ)^{3}

(16 - 8 x^{\frac{1}{2}} + x)^{2}

3 x (3 x - 40 + 1 = 0)

\frac{7 x + 10}{( x + 1 ) ( x ^{2} - 4 )}
