New Formulas for Solving Quadratic Equations over Certain Finite Fields
We present new formulas for solving quadratic equations with distinct roots in certain finite fields. We develop in detail formulas for solving such quadratics over GF (4), GF(16), and GF (256) and the approach we take is applicable for solving quadratics over GF (2k), with k a power of 2.
