Problem #1: Let Q(x) = 63x14x14x-24x1x2-24x1x3 - 32x2x3. Find a unit vector x in R³ whose first entry is positive at which Q(x) is minimized, subject to xx = 1. [Hint: The eigenvalues of the matrix of the quadratic form Q are 2, -33, and 66.] Enter the components of x (in order) into the answer box below, separated with commas.
