Question

x2+15-8x÷3x ayudenme​

Answer 1

Supongo que quisiste decir:

$\frac{ {x}^{2} + 15 - 8x }{3x}$

Entonces :

$\frac{ {x}^{2} }{3x} + \frac{15}{3x} - \frac{8x}{3x}$

$\frac{ {x}^{2} }{3x} = \frac{x}{3} \times \frac{x}{x} = \frac{x}{3} \times 1 = \frac{x}{3} \\ \\ \frac{15}{3x} = \frac{3}{3} \times \frac{5}{x} = 1 \times \frac{5}{x} = \frac{5}{x} \\ \\ \frac{8x}{3x} = \frac{8}{3} \times \frac{x}{x} = \frac{8}{3} \times 1 = \frac{8}{3}$

Respuesta:

$\frac{x}{3} + \frac{5}{x} - \frac{8}{3}$
