Question
**Problem Statement:**

Find the maximum and minimum values, and a vector where each occurs, of the quadratic form subject to the constraint.

\[ w = 6x^2 - 3y^2 - 3z^2 + 12xy - 12xz + 24yz; \quad x^2 + y^2 + z^2 = 1 \]

**Solutions:**

The constrained maximum of \(\_\_\_\_\_\_\) occurs at two sets of coordinates. The set of coordinates with the smaller \(x\) value is \((x, y, z) = (\_\_\_\_\_\_, \_\_\_\_\_\_, \_\_\_\_\_\_)\), and the set of coordinates with the larger \(x\) value is \((x, y, z) = (\_\_\_\_\_\_, \_\_\_\_\_\_, \_\_\_\_\_\_)\).

The constrained minimum of \(\_\_\_\_\_\_\) occurs when \((x, y, z) = (\_\_\_\_\_\_, \_\_\_\_\_\_, \_\_\_\_\_\_)\).

**Note:** Replace blanks with the correct values once calculated.
