Solucionar c+12/(12-c)^2+12/12c-c^2

$$\frac { c + 12 } { ( 12 - c ) ^ { 2 } } + \frac { 12 } { 12 c - c ^ { 2 } }$$

Calcular

$$\frac{c^{2}+144}{c\left(12-c\right)^{2}}$$

Solución en pasos breves

Factorice 12c-c^{2}.

$$\frac{c+12}{\left(12-c\right)^{2}}+\frac{12}{c\left(-c+12\right)}$$

Para sumar o restar expresiones, expándalas para que sus denominadores sean iguales. El mínimo común múltiplo de \left(12-c\right)^{2} y c\left(-c+12\right) es c\left(-c+12\right)\left(-c+12\right)^{2}. Multiplica \frac{c+12}{\left(12-c\right)^{2}} por \frac{c\left(-c+12\right)}{c\left(-c+12\right)}. Multiplica \frac{12}{c\left(-c+12\right)} por \frac{\left(-c+12\right)^{2}}{\left(-c+12\right)^{2}}.

$$\frac{\left(c+12\right)c\left(-c+12\right)}{c\left(-c+12\right)\left(-c+12\right)^{2}}+\frac{12\left(-c+12\right)^{2}}{c\left(-c+12\right)\left(-c+12\right)^{2}}$$

Como \frac{\left(c+12\right)c\left(-c+12\right)}{c\left(-c+12\right)\left(-c+12\right)^{2}} y \frac{12\left(-c+12\right)^{2}}{c\left(-c+12\right)\left(-c+12\right)^{2}} tienen el mismo denominador, sume sus numeradores para sumarlos.

$$\frac{\left(c+12\right)c\left(-c+12\right)+12\left(-c+12\right)^{2}}{c\left(-c+12\right)\left(-c+12\right)^{2}}$$

Haga las multiplicaciones en \left(c+12\right)c\left(-c+12\right)+12\left(-c+12\right)^{2}.

Combine los términos semejantes en -c^{3}+12c^{2}-12c^{2}+144c+12c^{2}-288c+1728.

$$\frac{-c^{3}+12c^{2}-144c+1728}{c\left(-c+12\right)\left(-c+12\right)^{2}}$$

Factorice las expresiones que aún no se hayan factorizado en \frac{-c^{3}+12c^{2}-144c+1728}{c\left(-c+12\right)\left(-c+12\right)^{2}}.

$$\frac{\left(-c+12\right)\left(c^{2}+144\right)}{c\left(-c+12\right)\left(-c+12\right)^{2}}$$

Anula -c+12 tanto en el numerador como en el denominador.
