What is the number of solution(s) of the equation |√x – 2| + √x(√x – 4) + 2 = 0?(a) 2(b) 4(c) No solution(d) Infinitely many solutionsThis question was posed to me during an internship interview.This intriguing question originated from Applications of Quadratic Equations topic in division Complex Numbers and Quadratic Equations of Mathematics – Class 11

Answer» CORRECT option is (a) 2

Explanation: We have |√X – 2| + √x(√x – 4) + 2 = 0,

|√x – 2| + (√x)^2 – 4√x + 2 = 0

|√x – 2| + |√x -2|^2 – 2 = 0

|√x – 2| = -2, 1

Thus, √x – 2 = +1, -1 or x = 1, 9
