Best ResponseYou've already chosen the best response.1square root (x+6) = x Square both sides x+6 = x^2 x^2x6 = 0 (x3)(x+2) = 0 x3 = 0 x = 3 x+2 = 0 x = 2 Even though x=3 and x=2 the only solution is x=3 because of the following: square root (3+6) = 3 Square root 9 = 3 which is a true statement square root (2+6) = square root 4 = 2 but the second solution states that x=2 and therefore the square root 4 does not equal 2
