Solving Equations using Quadratic Formula
b^2-4ac < 0
this type of quadratic equation has two imaginary solutions related parabola does not cross x axis |
b^2-4ac = 0
this type of quadratic equation has one rational solution (it repeats) related parabola does not cross x axis, it bounces off of it |
b^2-4ac = perfect square
this type of quadratic equation has two rational solutions related parabola crosse the x axis in two distinct places |
if b^2-4ac is not perfect square and positive, then this type of quadratic equation has two irrational solutions
related parabola crosse the x axis in two distinct places |
