$\lim_{x\to\infty }\left(\frac{\frac{4x+8}{x^2}}{\frac{6x^2+7x-7}{x^2}}\right)$
Learn how to solve differential equations problems step by step online. Find the limit of (4x+8)/(6x^2+7x+-7) as x approaches infinity. As it's an indeterminate limit of type \frac{\infty}{\infty}, divide both numerator and denominator by the term of the denominator that tends more quickly to infinity (the term that, evaluated at a large value, approaches infinity faster). In this case, that term is . Separate the terms of both fractions. Simplify the fraction . Simplify the fraction by x.
