Question

What is true about the solutions of a quadratic equation when the radicand of the quadratic formula is zero?

No real solutions

Two identical rational solutions

Two different rational solutions

Two irrational solutions

Answer 1

lets give it a shot:\[x=\frac{-b\pm\sqrt{0}}{2a}\]

Answer 2

-b+0 = -b
-b-0 = -b

so that simplifies to what ...\[x=\frac{-b}{2a}\]

Answer 3

two identical solutions (x = -b/2a)

Answer 4

thnk u

Answer 5

i was hoping they could come to that realization on their own :)
