I came across a question --> Solve By using hit and trial, its easy, and answer will be 5. But I sat down to solve it and it came as :- Can you explain why 165 is coming in the solution of the polynomial I expanded, but not as the answer? And if theres a mistake in my process, please tell me.

√(2x-6) + √(x+4) = 5 (x-5)(x-165) = 0 x = 5 & x = 165 answer is x = 5 because only x = 5 satisfy the given equation . remember one things when you solve this type of problems just cross check putting the value of x.
