## Step-by-step Solution

Problem to solve:

$\lim_{x\to-2}\left(3x^2-x-10\right)=8$

Choose the solving method

1

Evaluate the limit $\lim_{x\to-2}\left(3x^2-x-10=8\right)$ by replacing all occurrences of $x$ by $-2$

$3\cdot {\left(-2\right)}^2-1\cdot -2-10=8$

Learn how to solve limits by direct substitution problems step by step online.

$3\cdot {\left(-2\right)}^2-1\cdot -2-10=8$

Learn how to solve limits by direct substitution problems step by step online. Find the limit of 3x^2-x-10=8 as x approaches -2. Evaluate the limit \lim_{x\to-2}\left(3x^2-x-10=8\right) by replacing all occurrences of x by -2. Simplifying, we get. So the limit results in.
