If `x-(2)/(3)` and `x+3` are factors of the quadratic polynomial `ax^(2)+7x+b`, then find the values of `a` and `b`.

Explanation

To solve the problem, we need to find the values of \( a \) and \( b \) in the quadratic polynomial \( ax^2 + 7x + b \) given that \( x - \frac{2}{3} \) and \( x + 3 \) are factors of this polynomial.

### Step-by-Step Solution:

1. **Identify the Roots:**
The factors of the polynomial imply that the roots of the polynomial are:
\[
x = \frac{2}{3} \quad \text{and} \quad x = -3
