1 real and 1 complex solution

Answer 1

What do you think it is?

Answer 2

I think its A

Answer 3

Nope. Have another attempt

Answer 4

It should be 2 real solutions.
discriminant >0, the equation has two real solutions.
That is a rule you need to memorize.

Answer 5

Discriminant=0, it has one real solution.
Discriminant<0, two complex solutions.

Answer 6

So any number other that 0 has 2 real solutions?

Answer 7

<0, two complex solutions

Answer 8

Oh okay
