What will be the sum of the real roots of the equation x^2 + 5|x| + 6 = 0?(a) Equal to 5(b) Equal to 10(c) Equal to -5(d) Does not existThis question was addressed to me in semester exam.This intriguing question originated from Applications of Quadratic Equations in division Complex Numbers and Quadratic Equations of Mathematics – Class 11

Answer»

The CORRECT CHOICE is (d) Does not exist

The explanation is: Since, x^2, 5|x| and 6 are POSITIVE,

So, x^2 + 5|x| + 6 = 0 does not have any REAL root

Therefore, sum does not exist.
