To solve the equation

\[ 2 + \frac{x^2}{5} = \frac{x}{6}, \]

first, we can eliminate the fractions by finding a common denominator for the entire equation. The common denominator of 5 and 6 is 30. Multiply every term of the equation by 30:

\[ 30 \cdot 2 + 30 \cdot \frac{x^2}{5} = 30 \cdot \frac{x}{6}. \]

This simplifies to:

\[ 60 + 6x^2 = 5x. \]

Next, we rearrange the equation into standard quadratic form:

\[ 6x^2 - 5x + 60 = 0. \]

Now, we apply the quadratic formula, given by

\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}, \]

where in our case \(a = 6\), \(b = -5\), and \(c = 60\). First, we calculate the discriminant \(b^2 - 4ac\):

\[ b^2 - 4ac = (-5)^2 - 4(6)(60) = 25 - 1440 = -1415. \]

Since the discriminant is negative, the roots will be complex. Now we substitute into the quadratic formula:

\[ x = \frac{-(-5) \pm \sqrt{-1415}}{2(6)} = \frac{5 \pm \sqrt{1415}i}{12}. \]

Thus, simplifying the expression, we have:

\[ x = \frac{5}{12} \pm \frac{\sqrt{1415}}{12} i. \]

Therefore, the roots of the equation in simplest form are:

\[ \frac{5}{12} \pm \frac{\sqrt{1415}}{12} i. \]

So the answer can be expressed as:

\[ \frac{5}{12} \pm \frac{\sqrt{1415}}{12} i. \]

Thus, the answer is:

\[ \frac{5}{12} \pm \frac{\sqrt{1415}}{12} i. \]

Final answer:

The roots of the equation in simplest form are \(\frac{5}{12} \pm \frac{\sqrt{1415}}{12} i\).
