?

Answer 16

Do you want to find the value of x? I'm guessing that you're confused how there are two values of x.

Answer 17

Yeaaah pretty much.

Answer 18

OK, now this is a quadratic equation, which means the degree is 2.You get that?

Answer 19

Oh, wait, I think I got it, is it this? 9-30+16=-5?

Answer 20

No, you don't need to confuse yourself.

Answer 21

I'm explaining why there are two values of x. You understand the part about the degree.

Answer 22

Yeaah sure!

Answer 23

OK, so basically, the concept is that the degree of the equation denotes the number of solutions it has. You interpret it like this, a quadratic equation will have two values, an equation with degree 3 will have 3 solutions and so on.
