Solve the inequality
χ<0
Alternative Form
χ∈(−∞,0)
Evaluate
−∞<χ2<0
Separate into two inequalities
{−∞<χ×2χ×2<0
Solve the inequality
More Steps
Evaluate
−∞<χ×2
Use the commutative property to reorder the terms
−∞<2χ
Swap the sides of the inequality
2χ>−∞
Divide both sides
22χ>2−∞
Divide the numbers
χ>2−∞
Divide the numbers
χ>−∞
