Pregunta: limx→∞9x2-3x+84x2+7x-30

Divide the numerator and denominator by the highest power of $\mathrm{x}$ in the denominator, which is ${\mathrm{x}}^2$ .

$\underset{\mathrm{x}\to \mathrm{\infty }}{lim}\left(\frac{\frac{9{\mathrm{x}}^2}{{\mathrm{x}}^2}+\frac{-3\mathrm{x}}{{\mathrm{x}}^2}+\frac{8}{{\mathrm{x}}^2}}{\frac{4{\mathrm{x}}^2}{{\mathrm{x}}^2}+\frac{7\mathrm{x}}{{\mathrm{x}}^2}+\frac{-30}{{\mathrm{x}}^2}}\right)$
