WebThe discriminant is B^2 - 4AC, which is (-2a)^2 - 4 (2a^2+1) = 4a^2 - 8a^2 - 4 = -4 (a^2 + 1). What does this mean? Well, a^2 is always non-negative (i.e. zero or positive) so the bracketed term a^2+1 is always positive. Thus the discriminant is always -4 times a positive number, so it is always negative. WebA quadratic equation in "Standard Form" has three coefficients: a, b, and c. Changing either a or c causes the graph to change in ways that most people can understand after a little …
