WebSince we want the determinant to be nonzero for the gradients to be linearly independent, we need to solve the equation: 72(x1 + x2 + x3)(x1^2 + x2^2 + x3^2) - 36(x1 + x2 + x3) - 12x1x2x3 + 3 ≠ 0. Unfortunately, this equation is difficult to solve analytically, and we will need to resort to numerical methods or approximations.
