x = -2 or x = 1
x = 0 or x = -3
x = 2 or x = 1
x = 0 or x = 3
Correct answer is D
32x−2−28(3x−2)+3=0
32x32−28.3x32+3=0
32x9−28.3x9+3=0
let p = 3x
p29−28p9+3=0
multiply through by 9
p2 - 28p + 27 = 0
p2 - p - 27p + 27 = 0
p (p - 1) - 27(p - 1) = 0
(p-1)(p-27) = 0
p = 1 or 27
when p = 1
p = 3x
3x = 1
3x = 30
x = 0
when p = 27
3x = 27
3x = 33
x = 3
