x^{2}<56
Add 56 to both sides.
x^{2}<\left(2\sqrt{14}\right)^{2}
Calculate the square root of 56 and get 2\sqrt{14}. Rewrite 56 as \left(2\sqrt{14}\right)^{2}.
|x|<2\sqrt{14}
Inequality holds for |x|<2\sqrt{14}.
x\in \left(-2\sqrt{14},2\sqrt{14}\right)
Rewrite |x|<2\sqrt{14} as x\in \left(-2\sqrt{14},2\sqrt{14}\right).
