Question

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

No real solutions

Two identical rational solutions

Two different rational solutions

Two irrational solutions

Answer 1

I think c is the correct one.

Answer 2

(a) applies when the radicand is a negative number
(b) applies when the radicand is 0

Answer 3

Okay thanks!

Answer 4

Sorry, but on second thought, I'm going for (d)

Answer 5

Taking this example,
x=-8 plusminus sqrt (144) / 2
x= -8 plusminus 12 /2
x = (-8+12)/2 and x = (-8-12)/2
x = 2 and -10
Two irrational solutions. So (d) is the answer :)

Answer 6
