Step 1
So, we can set up the following equations: 1 = x -8 = y -4 = z Therefore, the values of y and z are -8 and -4, respectively. Now, let's move on to the second matrix. For a matrix to be skew-symmetric, it must satisfy the condition A = -A^T. So, we can set up Show more…

Find the symmetric matrix $A$ belonging to each of the following quadratic forms: (a) $\quad q(x, y, z)-2 x^{2}-8 x y+y^{2}-16 x z+14 y z+5 z^{2}$ (b) $q(x, y, z)=x^{2}-x z+y^{2}$ (c) $\quad q(x, y, z)=x y+y^{2}+4 x z+z^{2}$ (d) $\quad q(x, y, z)=x y+y z$
Find the symmetric matrix that corresponds to each of the following quadratic forms: (a) $q(x, y, z)=3 x^{2}+4 x y-y^{2}+8 x z-6 y z+z^{2}$ (b) $q^{\prime}(x, y, z)=3 x^{2}+x z-2 y z$ (c) $q^{\prime \prime}(x, y, z)=2 x^{2}-5 y^{2}-7 z^{2}$
Let x be a 4 x 1 vector. Find symmetric matrices A1 and A2 such that x'A1x = (x1 + x2 - 2x3)^2 + (x3 - x4)^2, x'A2x = (x1 - x2 - x3)^2 + (x1 + x2 - x4)^2.
