Answer 8

http://www.wolframalpha.com/input/?i=solve%20for%20x%20%3A%20sqrt%7B3x%2B24%7D%20-%20sqrt%7Bx%2B21%7D%3D1&t=crmtb01

Answer 9

(x+21)= -1 +2(sqrt(3x+24)) - (sqrt(3x+24))^2
(x-3x+22-24)/2= sqrt(3x+24)
(-2x-2)^2= (3x+24)
4x^2-8x+4 = 3x+24
4x^2-11x-20 = 0
so yeah 4 having trouble factoring the last part
