can you please provide explanations A2. Use Bordered Hessians to determine the sign properties (definiteness) of the following con-strained quadratic forms:Q(x1, x2, x3) = x² + x² + x² + 4x1x2 - 2x1x3 subject to x₁+x2+x3 = 0 and -x₁+x2+x3 =0,Q(x, y, z) = x² + y² - 6xz + 4yz subject to -x+y+z=0.

To determine the definiteness of the quadratic forms subject to the given constraints, we can use…

Answered: Q(x₁, x2, x3) = x² + x² + x² + 4x₁x2 −…
