If the absolute value x + a = 0 of the equation x2-2 of X has four different real roots, find a zero point of the range function X3 + x-3 of A

If the absolute value x + a = 0 of the equation x2-2 of X has four different real roots, find a zero point of the range function X3 + x-3 of A

|Four different real roots of X | ^ 2-2 | + a = 0 have two unequal roots for the equation of | x |
Discriminant > 0 4-4a > 0 a
