A Practical Approach to Quadratic Equations.
Light, Peter
Mathematics in School, v12 n1 p12-13 Jan 1983
The usual methods for solving quadratic equations are noted to require either the use of numerical formula or curve plotting on graph paper. The method described here enables pupils to solve equations using only a 45 degree setsquare, graph paper, and a pencil for those which have both real roots and real coefficients. (Author/MP)
