Answer 1

This is my last one. I am completely lost.

Answer 2

@Directrix

Answer 3

3x^2=2x^2-2x-1

3x^2-2x^2+2x+1 = 0

x^2 + 2x + 1 = 0

I'll let you finish

Answer 4

I honestly dont know what to do. Do i solve for x?

Answer 5

If so, it is 1

Answer 6

yes, but factor first

Answer 7

(X+1)^2=0

Answer 8

good, so x = ???

Answer 9

1?

Answer 10

no

Answer 11

Let's test it

(x+1)^2=0

(1+1)^2=0 .. plug in x = 1

2^2 = 0

4 = 0 ... this is FALSE, so x = 1 is NOT a solution

Answer 12

-1

Answer 13

yep

Answer 14

Check:

(x+1)^2=0

(-1+1)^2=0 .. plug in x = -1

(0)^2 = 0

0 = 0 ... this is TRUE, so x = -1 is definitely a solution

Answer 15

Sory, had tha the first time, accidentl forgot the negative

Answer 16

Now, is this a complex #?
