To find the value of the function $g(x) = x^2 + 2x - 2$ at $x = 1.5$, we substitute $x = 1.5$ into the function.

$g(1.5) = (1.5)^2 + 2(1.5) - 2$

Let's calculate it step by step:

1. Calculate $(1.5)^2$: $(1.5)^2 = 2.25$

2. Calculate $2 \times 1.5$: $2 \times 1.5 = 3$

3. Combine these results: $g(1.5) = 2.25 + 3 - 2$

4. Simplify: $g(1.5) = 2.25 + 3 - 2 = 3.25$

So, the value of $g(1.5)$ is $3.25$.
