hmm ok

Answer 17

ok I am searching

Answer 18

-3x^2 + 9x=1
-3x^2 + 9x -1 =0
3x^2 -9x +1 =0
x^2 - 3x +1/3 =0

Answer 19

Answer 22

(x^2 - 3x + 9/4) -9/4 +1/3 =0

Answer 23

(x-3/2)^2 -9/4 +1/3 =0

Answer 24

(x-3/2)^2 - 27/12 + 4/12 = 0

Answer 25

(x-3/2)^2 - 23/12 = 0
(x-3/2)^2 = 23/12
x-3/2 = sqrt(23/12)
x = sqrt(23/12) + 3/2

Answer 26

did you follow all of that?

Answer 27

x is also equal to -sqrt(23/12) + 3/2

Answer 28

I think so...

Answer 29

just go through all my steps one by one and you'll see how I've come to the final two answers

Answer 30

He is confused
