Mathematics - Quadratic Equation Question with Solution | TestHub

$A=\left\{x:x\in \left(-\mathrm{2,2}\right)\right\}$

$B=\left\{x:x\in (-\infty ,-1]\cup [5,\left.\infty \right)\right\}$

$A\cap B=\left\{x:x\in (-2,-1]\right\}$

$A\cup B=\left\{x:x\in \left(-\infty ,2\right)\cup \left[5,\infty )\right.\right\}$

$A-B=\left\{x:x\in \left(-\mathrm{1,2}\right)\right\}$

$B-A=\left\{x:x\in \left(-\infty ,\left.-2\right]\cup \right.\left[5,\left.\infty \right)\right.\right\}$
