See attachments.

Answer 2

So it would be c?

Answer 3

Let me crank it out. Just a moment.

Answer 4

If this is c: --> 2 irrational roots --> then No.

Answer 5

Look at the quadratic:

x^2 + 6x + 9 = 0

It factors:

(x + 3)* (x + 3) = 0

@ShantelT1 What are the two solutions?

Answer 6

i dont know :(

Answer 7

Yes, you do.

Look:

(x + 3)* (x + 3) = 0

x + 3 = 0 OR x + 3 = 0

x = ? OR x = ?

Answer 8

What added to 3 gives a sum of zero?

Answer 9

3

Answer 10

3 + 3 = 6, not zero.

Try again.

What added to 3 gives a sum of zero?

Answer 11

-3

Answer 12

x + 3 = 0 OR x + 3 = 0

x = -3 OR x = -3

So, which option is this?

Answer 13

-3 is considered to be a double root.

Answer 14

So it's 1 ratopma;?
