On quadratic inequalities of one variable Given that the square of equation x + 2mx + 2-m = 0 has two real roots with the same sign but not equal, what is the value range of real number m

On quadratic inequalities of one variable Given that the square of equation x + 2mx + 2-m = 0 has two real roots with the same sign but not equal, what is the value range of real number m

Discriminant = 4m ^ 2-4 (2-m) > 0
2-m > 0
