Let's first express the given polynomials clearly:

The first polynomial is:
\[
\frac{7}{8}x^2 - \frac{6}{5}x + 2
\]

The second polynomial is:
\[
-2 + 4x - \frac{3}{8}x^2
\]

Now, let's add the polynomials:

1. Combine the \(x^2\) terms:
\[
\frac{7}{8}x^2 - \frac{3}{8}x^2 = \frac{4}{8}x^2 = \frac{1}{2}x^2
\]

2. Combine the \(x\) terms:
\[
-\frac{6}{5}x + 4x = -\frac{6}{5}x + \frac{20}{5}x = \frac{14}{5}x
\]

3. Combine the constant terms:
\[
2 - 2 = 0
\]

Thus, the sum of the polynomials is:
\[
\frac{1}{2}x^2 + \frac{14}{5}x
\]
