Cross out the one FALSE statement.
a^2 + bx + c = O is a quadratic equation in standard form.
b2 - 4ac is called the discriminant.
If b2 - 4ac = O, then there is one real solution.
If b2 - 4ac > O, then there are two real solutions.
If b2 - 4ac < O, then there is no real solution.
If (x - a) (x + b) = 0, then x = a or - b
A quadratic equation has degree four.
