\frac{x+2}{\left(x-1\right)\left(x+5\right)}-\frac{3}{\left(x+1\right)\left(x+5\right)}
Factorice x^{2}+4x-5. Factorice x^{2}+6x+5.
\frac{\left(x+2\right)\left(x+1\right)}{\left(x-1\right)\left(x+1\right)\left(x+5\right)}-\frac{3\left(x-1\right)}{\left(x-1\right)\left(x+1\right)\left(x+5\right)}
Para sumar o restar expresiones, expándalas para que sus denominadores sean iguales. El mínimo común múltiplo de \left(x-1\right)\left(x+5\right) y \left(x+1\right)\left(x+5\right) es \left(x-1\right)\left(x+1\right)\left(x+5\right). Multiplica \frac{x+2}{\left(x-1\right)\left(x+5\right)} por \frac{x+1}{x+1}. Multiplica \frac{3}{\left(x+1\right)\left(x+5\right)} por \frac{x-1}{x-1}.
\frac{\left(x+2\right)\left(x+1\right)-3\left(x-1\right)}{\left(x-1\right)\left(x+1\right)\left(x+5\right)}
Como \frac{\left(x+2\right)\left(x+1\right)}{\left(x-1\right)\left(x+1\right)\left(x+5\right)} y \frac{3\left(x-1\right)}{\left(x-1\right)\left(x+1\right)\left(x+5\right)} tienen el mismo denominador, reste sus numeradores para restarlos.
\frac{x^{2}+x+2x+2-3x+3}{\left(x-1\right)\left(x+1\right)\left(x+5\right)}
Haga las multiplicaciones en \left(x+2\right)\left(x+1\right)-3\left(x-1\right).
\frac{x^{2}+5}{\left(x-1\right)\left(x+1\right)\left(x+5\right)}
Combine los términos semejantes en x^{2}+x+2x+2-3x+3.
\frac{x^{2}+5}{x^{3}+5x^{2}-x-5}
Expande \left(x-1\right)\left(x+1\right)\left(x+5\right).
\frac{x+2}{\left(x-1\right)\left(x+5\right)}-\frac{3}{\left(x+1\right)\left(x+5\right)}

Multiplica \frac{x+2}{\left(x-1\right)\left(x+5\right)} por \frac{x+1}{x+1}. Multiplica \frac{3}{\left(x+1\right)\left(x+5\right)} por \frac{x-1}{x-1}.
\frac{\left(x+2\right)\left(x+1\right)-3\left(x-1\right)}{\left(x-1\right)\left(x+1\right)\left(x+5\right)}
Como \frac{\left(x+2\right)\left(x+1\right)}{\left(x-1\right)\left(x+1\right)\left(x+5\right)} y \frac{3\left(x-1\right)}{\left(x-1\right)\left(x+1\right)\left(x+5\right)} tienen el mismo denominador, reste sus numeradores para restarlos.
\frac{x^{2}+x+2x+2-3x+3}{\left(x-1\right)\left(x+1\right)\left(x+5\right)}
Haga las multiplicaciones en \left(x+2\right)\left(x+1\right)-3\left(x-1\right).
