x^{2}<\frac{-4}{-4}
Divide both sides by -4. Since -4 is negative, the inequality direction is changed.
x^{2}<1
Divide -4 by -4 to get 1.
x^{2}<1^{2}
Calculate the square root of 1 and get 1. Rewrite 1 as 1^{2}.
|x|<1
Inequality holds for |x|<1.
x\in \left(-1,1\right)
Rewrite |x|<1 as x\in \left(-1,1\right).
