Abstract :
A set of simultaneous quadratic equations with unknown coefficients is considered. The motivation for studying the equations is presented. Indeterminacy and identifiability are considered. A main lemma and three theorems are presented. A comparison with the well-known simultaneous diagonalization problem is given
