Solving the Equation (x-5)(x-6) = 25/24

This article will guide you through the steps of solving the equation (x-5)(x-6) = 25/24.

1. Expanding the Equation

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

(x-5)(x-6) = x² - 6x - 5x + 30 = x² - 11x + 30

Now our equation becomes: x² - 11x + 30 = 25/24

2. Bringing All Terms to One Side

To solve this quadratic equation, we need to bring all the terms to one side:

x² - 11x + 30 - 25/24 = 0

3. Simplifying the Equation

To simplify, let's find a common denominator for 30 and 25/24:

x² - 11x + (720 - 25)/24 = 0

x² - 11x + 695/24 = 0

4. Solving the Quadratic Equation

Now we have a standard quadratic equation in the form ax² + bx + c = 0. We can solve this using the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

In our equation, a = 1, b = -11, and c = 695/24. Let's substitute these values into the formula:

x = (11 ± √((-11)² - 4 * 1 * (695/24))) / (2 * 1)

x = (11 ± √(121 - 695/6)) / 2

x = (11 ± √(121 - 115.83)) / 2

x = (11 ± √5.17) / 2

5. Finding the Solutions

Finally, we can calculate the two possible solutions for x:

x₁ = (11 + √5.17) / 2 ≈ 6.29

x₂ = (11 - √5.17) / 2 ≈ 4.71

Therefore, the solutions to the equation (x-5)(x-6) = 25/24 are x ≈ 6.29 and x ≈ 4.71.
