There are 5 quadratics below. Four of them have two distinct roots each. The other has only one distinct root; find the value of that root.
2x^2 - 4x + 8
2x^2 - 12x + 24
-x^2 + 6x + 9
3x^2 - 6x + 3
8x^2 - 4x + 1
+36915 To have 1 root the discriminant will = 0 b2 - 4ac =0 find which one has that, then use Quadratic Formula to find that root.
