Matrix X and A are symmetrical and they are 3 x 3. I know the matrix A. How to calculate matrix X from the equation X^T * X = A ???

Let Then So if A is given as, say, We must have , , , , , Six quadratic equations to solve for a, b, c, d, e, f.

I started to solve it, but it's not easy to solve such quadratic equations.
