Question

what are my solutions if i get 4 as my discriminate

Answer 1

The two possible square roots are 2 & -2. So the solutions will be: \(\frac{-b\pm2}{2a}\).

Answer 2

our teacher wants us to put 2 complex 2 real what is the difference between them

Answer 3

Huh? This equation doesn't have any complex solutions.

Answer 4

so it will be 2 real

Answer 5

Yes.

Answer 6

what will make it a complex solution

Answer 7

If discriminant is positive: 2 real. If zero: 1 real. If negative: 2 complex.

Answer 8

thanks

Answer 9

No problem.

Answer 10

wait will it always be 2 complex if it is negative

Answer 11

Yeah, say for example you get \(\sqrt{-4}\) as your discriminant. The two possible values of this are 2i and -2i.

Answer 12

good point thanks

Answer 13

You're welcome :)
