Discriminant of a QuadraticThe number D = b2 –4ac determined from the coefficients of the equation ax2 + bx + c = 0. The discriminant reveals what type of roots the equation has. Note: b2 –4ac comes from the quadratic formula.
Most students memorize the formula, identify the correct values for each variable, and successfully solve to find solutions for the equation, but few of them ever understand or appreciate the power of that piece of the formula called the discriminant. There are many additional applications for the...
