 Difficult Problems

Here, we show you a step-by-step solved example of limits by direct substitution. This solution was automatically generated by our smart calculator:

$\lim_{x\to2}\left(\frac{3x^2-4x-11}{2x+1}\right)$

Evaluate the limit $\lim_{x\to 2}\left(\frac{3x^2-4x-11}{2x+1}\right)$ by replacing all occurrences of $x$ by $2$

$\frac{3\cdot 2^2-4\cdot 2-11}{2\cdot 2+1}$

Multiply $2$ times $2$

$\frac{3\cdot 2^2-4\cdot 2-11}{4+1}$

Add the values $4$ and $1$

$\frac{3\cdot 2^2-4\cdot 2-11}{5}$

Multiply $-4$ times $2$

$\frac{3\cdot 2^2-8-11}{5}$

Subtract the values $-8$ and $-11$

$\frac{3\cdot 2^2-19}{5}$

Calculate the power $2^2$

$\frac{3\cdot 4-19}{5}$

Multiply $3$ times $4$

$\frac{12-19}{5}$

Subtract the values $12$ and $-19$

$-\frac{7}{5}$
