Full solution

Q. x+24x2+x+76x2=1 \sqrt{x+2-4 \sqrt{x-2}}+\sqrt{x+7-6 \sqrt{x-2}}=1
  1. Denote Square Root Terms: Let's denote the two square root terms as AA and BB, where A=x+24x2A = \sqrt{x+2-4\sqrt{x-2}} and B=x+76x2B = \sqrt{x+7-6\sqrt{x-2}}. The equation can then be written as A+B=1A + B = 1.
  2. Square Both Sides: We will square both sides of the equation to eliminate the square roots. This gives us (A+B)2=12(A + B)^2 = 1^2.
  3. Expand Left Side: Expanding the left side, we get A2+2AB+B2=1A^2 + 2AB + B^2 = 1.
  4. Substitute Expressions: Substitute back the expressions for AA and BB to get ((x+24(x2)))2+2(x+24(x2))(x+76(x2))+((x+76(x2)))2=1(\sqrt{(x+2-4\sqrt{(x-2)})})^2 + 2\sqrt{(x+2-4\sqrt{(x-2)})}\sqrt{(x+7-6\sqrt{(x-2)})} + (\sqrt{(x+7-6\sqrt{(x-2)})})^2 = 1.
  5. Simplify Squared Terms: Simplify the squared terms to get (x+24x2)+2(x+24x2)(x+76x2)+(x+76x2)=1(x+2-4\sqrt{x-2}) + 2\sqrt{(x+2-4\sqrt{x-2})(x+7-6\sqrt{x-2})} + (x+7-6\sqrt{x-2}) = 1.
  6. Combine Like Terms: Combine like terms to get x+x+24(x2)+76(x2)+2((x+24(x2))(x+76(x2)))=1x + x + 2 - 4\sqrt{(x-2)} + 7 - 6\sqrt{(x-2)} + 2\sqrt{((x+2-4\sqrt{(x-2)})(x+7-6\sqrt{(x-2)}))} = 1.
  7. Final Simplification: This simplifies to 2x+910x2+2(x+24x2)(x+76x2)=12x + 9 - 10\sqrt{x-2} + 2\sqrt{(x+2-4\sqrt{x-2})(x+7-6\sqrt{x-2})} = 1.
  8. Subtract and Divide: Subtract 99 from both sides to get 2x10(x2)+2((x+24(x2))(x+76(x2)))=82x - 10\sqrt{(x-2)} + 2\sqrt{((x+2-4\sqrt{(x-2)})(x+7-6\sqrt{(x-2)}))} = -8.
  9. Isolate Square Roots: Divide the entire equation by 22 to simplify, yielding x5x2+(x+24x2)(x+76x2)=4x - 5\sqrt{x-2} + \sqrt{(x+2-4\sqrt{x-2})(x+7-6\sqrt{x-2})} = -4.
  10. Reconsider Strategy: Now, we need to simplify the term under the square root. However, this is a complex expression, and it seems like we might have made a mistake in our approach. The term under the square root does not simplify easily, and we should have looked for a way to isolate one of the square roots before squaring the equation. This indicates that we need to reconsider our strategy.
