Problem

Solve the quadratic equation by using the square root property. (Enter your answers as a comma-separated list.) \[ \begin{array}{r} (x-5)^{2}=6 \\ x=\square \end{array} \]

Solution

Step 1 :Given the quadratic equation \((x-5)^{2}=6\).

Step 2 :Apply the square root property to both sides of the equation. The square root property states that if \(x^2 = a\), then \(x = \sqrt{a}\) or \(x = -\sqrt{a}\).

Step 3 :So, \(x-5 = \sqrt{6}\) or \(x-5 = -\sqrt{6}\).

Step 4 :Solving for \(x\) in both equations gives us two roots.

Step 5 :Root1 is \(x = 5 + \sqrt{6}\) which simplifies to \(x = 7.449489742783178\).

Step 6 :Root2 is \(x = 5 - \sqrt{6}\) which simplifies to \(x = 2.550510257216822\).

Step 7 :Final Answer: The solutions to the equation are \(x = \boxed{7.449489742783178}\) and \(x = \boxed{2.550510257216822}\).
