因式分解 (x^2-2x-3)/(x-1)

解答

因式分解

\frac{x ^{2} - 2 x - 3}{x - 1}

\frac{( x + 1 ) ( x - 3 )}{x - 1}

求解步骤

\frac{x ^{2} - 2 x - 3}{x - 1}

分解

x^{2} - 2 x - 3 : (x + 1) (x - 3)

= \frac{( x + 1 ) ( x - 3 )}{x - 1}

f a c t or (P - Q) - R

f a c t or 4 x^{(2)} + 3 x y - 15 y^{(2)}

f a c t or 6 x^{2} + 23 + 15

f a c t or 125 x^{3} + 27 x^{3}

f a c t or pq + q r + p s + rs
