The problem presented is the following limit:

\[
\lim_{{x \to 2}} \frac{x^2 + 4x + 12}{x^2 + 9x + 14} = 0
\]

To solve this, let's first evaluate the limit by direct substitution of \( x = 2 \).

### Step 1: Substitute \( x = 2 \) into the numerator and denominator.

#### Numerator:
\[
x^2 + 4x + 12 = 2^2 + 4(2) + 12 = 4 + 8 + 12 = 24
\]

#### Denominator:
\[
x^2 + 9x + 14 = 2^2 + 9(2) + 14 = 4 + 18 + 14 = 36
\]

### Step 2: Evaluate the limit.
Now substitute these values back into the fraction:

\[
\frac{24}{36} = \frac{2}{3}
\]

This is not equal to 0. Hence, the equation as written is incorrect if we expect the result to be 0.

### Conclusion:
The limit, as evaluated, equals \(\frac{2}{3}\), not 0. It seems there might be a mistake in the setup of the original equation.
