To solve the quadratic equation \((x - 7)^2 = 11\), we first take the square root of both sides:

\[
x - 7 = \pm \sqrt{11}
\]

This gives us two equations to solve:

1. \(x - 7 = \sqrt{11}\)
2. \(x - 7 = -\sqrt{11}\)

Now, we can solve each equation for \(x\):

1. From \(x - 7 = \sqrt{11}\):

\[
x = 7 + \sqrt{11}
\]

2. From \(x - 7 = -\sqrt{11}\):

\[
x = 7 - \sqrt{11}
\]

Now we have our two solutions:

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

### Now let's identify the values explicitly

Given that \(\sqrt{11} \approx 3.32\) (approximately):

1. Smaller solution:
\[
x = 7 - \sqrt{11} \approx 7 - 3.32 = 3.68
\]

2. Larger solution:
\[
x = 7 + \sqrt{11} \approx 7 + 3.32 = 10.32
\]

Thus, the final answers for the two solutions to the quadratic equation are:

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