Question

Simplifique as frações algébricas : $\frac{xm}{m²-mx}$

Answer 1

$\frac{xm}{m^{2}-mx}=\frac{\not m \cdot x}{\not m \cdot \left(m-x \right )}\\ \\ = \boxed{\frac{x}{m-x}}$

Answer 2

$\dfrac{xm}{m.a^2 - mx}$

Corta os termos semelhantes:

$\dfrac{x \not m}{\not m.a^2 - \not m \ x} \\ \\ \\ => \dfrac{x }{a^2 - x}$
