Solving the Equation (x-3)(x-5) = -1

This equation presents a quadratic equation in factored form. Let's break down how to solve it.

1. Expand the Equation

First, we need to expand the left side of the equation:

(x-3)(x-5) = -1 x² - 8x + 15 = -1

2. Move Constant Term to the Left Side

To get a standard quadratic form, move the constant term from the right side to the left:

x² - 8x + 15 + 1 = 0 x² - 8x + 16 = 0

3. Factor the Quadratic Expression

The left side of the equation is now a perfect square trinomial:

(x - 4)² = 0

4. Solve for x

Take the square root of both sides:

x - 4 = 0

Finally, solve for x:

x = 4

Solution

Therefore, the solution to the equation (x-3)(x-5) = -1 is x = 4.

This means that when you substitute x = 4 back into the original equation, it will be true.
