Here, we show you a step-by-step solved example of limites par substitution directe. This solution was automatically generated by our smart calculator:
Evaluate the limit $\lim_{x\to2}\left(\frac{3x^2-4x-11}{2x+1}\right)$ by replacing all occurrences of $x$ by $2$
Apply the formula: $ab$$=ab$, where $ab=2\cdot 2$, $a=2$ and $b=2$
Apply the formula: $a+b$$=a+b$, where $a=4$, $b=1$ and $a+b=4+1$
Apply the formula: $ab$$=ab$, where $ab=-4\cdot 2$, $a=-4$ and $b=2$
Apply the formula: $a+b$$=a+b$, where $a=-8$, $b=-11$ and $a+b=3\cdot 2^2-8-11$
Apply the formula: $a^b$$=a^b$, where $a=2$, $b=2$ and $a^b=2^2$
Apply the formula: $ab$$=ab$, where $ab=3\cdot 4$, $a=3$ and $b=4$
Apply the formula: $a+b$$=a+b$, where $a=12$, $b=-19$ and $a+b=12-19$
