Question

Colocando o fator comum em evidencia , simplifique as frações algébricas:
a)$\frac{6x + 12}{6x^2+6}$
b)$\frac{3x^2+6x}{x^3+2x^2}$
Obrigadaaaaaaaaaaaaaaa!!!

Answer 1

$a) \frac{6x+12}{6x^2+6} = \frac{6(x+2)}{6(x^2+1)} = \frac{x+2}{x^2+1} \\ b) \frac{3x^2+6x}{x^3+2x^2} = \frac{3x(x+2)}{x^2(x+2)} = \frac{3x}{x^2} = \frac{3}{x}$
