## Problem 7.17

### Objective
Show that all the following are equivalent:

### Equations
(a) \( x^2 - 5x + 6 = 0 \)

(b) \( (x - 2)(x - 3) = 0 \)

(c) \( x - 2 = 0 \) or \( x - 3 = 0 \)

(d) \( x = 2 \) or \( x = 3 \)

### Explanation
- **Equation (a)** is a quadratic equation in standard form, which needs to be solved to find the values of \( x \).
- **Equation (b)** expresses the quadratic equation in factored form, setting the product of two linear factors to zero.
- **Equation (c)** separates the factored equation into individual equations showing the principle of zero-product property.
- **Equation (d)** provides the solutions or roots of the quadratic equation, showing the values of \( x \) that satisfy the equation.
