Applying rationalisation
$\lim_{x\to\infty }\left(\left(\sqrt{x^2-8x+1}+x\right)\frac{\sqrt{x^2-8x+1}-x}{\sqrt{x^2-8x+1}-x}\right)$

$\lim_{x\to\infty }\left(\left(\sqrt{x^2-8x+1}+x\right)\frac{\sqrt{x^2-8x+1}-x}{\sqrt{x^2-8x+1}-x}\right)$
Learn how to solve limits to infinity problems step by step online. Find the limit of (x^2-8x+1)^(1/2)+x as x approaches infinity. Applying rationalisation. Multiply and simplify the expression within the limit. Cancel like terms x^2 and -x^2. 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 .
