<PRE><B>Question 663418</B>
sqrt(5x-7) + sqrt(2x+8) +2 = 0 
-------
sqrt(5x-7) = -[sqrt(2x+8)+2)
----
Square both sides:
5x-7 = 2x+8 + 4sqrt(2x+8)+4
----
3x-19 = 4sqrt(2x+8)
----
Square both sides:
9x^2 - 114x + 361 = 16(2x+8)
9x^2 - 114x + 361 = 32x + 128
----
9x^2 -146x + 233 = 0
----
Use the Quadratic formula to get:
x = 14.428
