To solve this equation, we can use algebraic manipulation:
1. Start by isolating the square root term on one side of the equation:
sqrt(3-x) = x + sqrt(2-x)
2. Square both sides of the equation to eliminate the square root:
3 - x = x^2 + 2 - x + 2x*sqrt(2-x)
3. Simplify the equation by combining like terms and isolating the radical term:
2x*sqrt(2-x) = x^2 + 1
4. Square both sides of the equation again to eliminate the radical:
4x^2 * (2-x) = (x^2 + 1)^2
5. Expand and simplify the equation:
-8x^3 + 4x^2 + 8x - 3 = 0
6. Factor the equation using synthetic division or trial and error:
(x-1)(-8x^2 + 12x + 3) = 0
7. Solve for x using the zero product property:
x = 1 or x = (3 + sqrt(33))/4 or x = (3 - sqrt(33))/4
Therefore, the solutions to the equation are x = 1, x = (3 + sqrt(33))/4, and x = (3 - sqrt(33))/4.
