The given problem involves completing the square for the quadratic function:

\[
h(x) = x^2 + 3x - 18
\]

The equation provided shows the function in vertex form, where we need to complete the square:

\[
h(x) = \left( x + 1.5 \right)^2 + \square
\]

### Step-by-step solution:

1. Start with the expression \(x^2 + 3x\).
2. The coefficient of \(x\) is 3. Divide this by 2: \(\frac{3}{2} = 1.5\), and then square it: \((1.5)^2 = 2.25\).
3. To complete the square, add and subtract 2.25 inside the equation:

\[
h(x) = (x^2 + 3x + 2.25) - 2.25 - 18
\]

4. Now factor the quadratic expression:

\[
h(x) = (x + 1.5)^2 - 2.25 - 18
\]

5. Simplify the constants:

\[
h(x) = (x + 1.5)^2 - 20.25
\]

Thus, the function in completed square form is:

\[
h(x) = (x + 1.5)^2 - 20.25
\]

So the missing values are:

\[
h(x) = 1(x + 1.5)^2 - 20.25
\]
