Can also factor. (x + 1)(x-3) = 0 y = x - 2x - 3 y Zero in discriminant b2-4ac=0 All two roots are real and equal Can also factor as: (x+2)(x+2)=0 Associated Graphs Negative number is discriminant. b 4ac0 No real root exists Cannot be factored further in real number system X Two Distinct x-intercepts. The graph also opens up as a > 0. ions: On Accessibility: Investigate W One (repeated) x-intercept. No x-intercepts. The graph also opens down as a < 0. The graph also opens up as a > 0.
