To solve the quadratic equation \((x-7)^2 = 11\), we first need to find the solutions by taking the square root of both sides.

Step 1: Rewrite the equation \[ (x - 7)^2 = 11 \]

Step 2: Take the square root of both sides \[ x - 7 = \pm \sqrt{11} \]

Step 3: Solve for \(x\)

  1. For the positive square root: \[ x - 7 = \sqrt{11} \implies x = 7 + \sqrt{11} \]

  2. For the negative square root: \[ x - 7 = -\sqrt{11} \implies x = 7 - \sqrt{11} \]

Now, we have our two solutions:

  1. \(x = 7 + \sqrt{11}\) (approximately 10.32)
  2. \(x = 7 - \sqrt{11}\) (approximately 3.68)

Identifying the smaller and larger solutions:

  • The smaller solution is \(x = 7 - \sqrt{11}\).
  • The larger solution is \(x = 7 + \sqrt{11}\).

Thus:

  • The smaller of the two solutions is \(x = 7 - \sqrt{11}\).
  • The larger of the two solutions is \(x = 7 + \sqrt{11}\).

Answers:

The smaller of the two solutions is \(x = 7 - \sqrt{11}\), and the larger of the two solutions is \(x = 7 + \sqrt{11}\).

whats the two number answers

To provide the two numerical answers for \(x = 7 - \sqrt{11}\) and \(x = 7 + \sqrt{11}\), we can calculate them as follows:

  1. Calculate \(7 - \sqrt{11}\):

    • The approximate value of \(\sqrt{11} \approx 3.3166\).
    • Therefore, \(7 - \sqrt{11} \approx 7 - 3.3166 \approx 3.6834\).
  2. Calculate \(7 + \sqrt{11}\):

    • Continuing with \(\sqrt{11} \approx 3.3166\).
    • Thus, \(7 + \sqrt{11} \approx 7 + 3.3166 \approx 10.3166\).

So, rounded to two decimal points:

  • The smaller solution is approximately \(3.68\).
  • The larger solution is approximately \(10.32\).

Final answers:

  • The smaller of the two solutions is \(x \approx 3.68\).
  • The larger of the two solutions is \(x \approx 10.32\).
