The answer is 7, your welcome :).
Factor out a 3x:
3x(x2+4x+6)
Since you can't factor out the quadratic that's as far as it goes:
Answer:
3x(x2+4x+6)
x + x + 3 + x - 8
3x - 5 = 55
3x = 60, x = 20
Since we put Julie as x, we put Janet at x + 3, and the brother is x - 8 (8 years younger)
Julie is 20
Janet (x + 3) = (20 + 3) = 23
Brother(x - 8) = (20 - 8) = 12
