Quick Reference. A mathematical model represented by a quadratic equation such as Y = aX2 + bX + c, or by a system of quadratic equations. The relationship between the variables in a quadratic equation is a parabola when plotted on a graph. Compare linear model. From: quadratic model in A Dictionary of Psychology ».Quadratics. A quadratic equation is an equation of the following form: ax2+bx+c=0 where x represents an unknown variable, a, b, and c are constants, and a≠0. The left side has all of the fancy numbers and variables, while the right side is 0. Because the term ax2 is raised to the second degree, it is called the quadratic term.where x represents an unknown value, and a, b, and c represent known numbers, where a ≠ 0. (If a = 0 and b ≠ 0 then the equation is linear, not quadratic.)The numbers a, b, and c are the coefficients of the equation and may be distinguished by respectively calling them, the quadratic coefficient, the linear coefficient and the constant coefficient or free term.
