Check that the values inside the radicals are positive.
=========================
sqrt(2x+7)-sqrt(3x-2)=2
------------
sqrt(2x+7) = sqrt(3x-2) + 2
Square both sides.
2x+7 = 3x-2 + 4 + 4sqrt(3x-2)
-x+5 = 4sqrt(3x-2)
Square again
x^2-10x+25 = 16(3x-2) = 48x-32
x^2 - 58x + 57 = 0
(x - 1)*(x - 57) = 0
x = 1
x = 57
