Impara online a risolvere i problemi di passo dopo passo. (x)->(-infinito)lim(((2x+1)^(1/2)-3)/(x-1)). Applicare la formula: \lim_{x\to c}\left(\frac{a}{b}\right)=\lim_{x\to c}\left(\frac{\frac{a}{sign\left(c\right)fgrow\left(b\right)}}{\frac{b}{sign\left(c\right)fgrow\left(b\right)}}\right), dove a=\sqrt{2x+1}-3, b=x-1, c=- \infty , a/b=\frac{\sqrt{2x+1}-3}{x-1} e x->c=x\to{- \infty }. Applicare la formula: \lim_{x\to c}\left(\frac{a}{b}\right)=\lim_{x\to c}\left(\frac{radicalfrac\left(a\right)}{radicalfrac\left(b\right)}\right), dove a=\frac{\sqrt{2x+1}-3}{-x}, b=\frac{x-1}{-x} e c=- \infty . Applicare la formula: \lim_{x\to c}\left(\frac{a}{b}\right)=\lim_{x\to c}\left(\frac{splitfrac\left(a\right)}{splitfrac\left(b\right)}\right), dove a=\frac{\sqrt{2x+1}-3}{-x}, b=\frac{x-1}{-x} e c=- \infty . Applicare la formula: \frac{a}{a}=1, dove a/a=\frac{-3}{-x}.
