[tex] |x| = \sqrt{3} = > x = \sqrt{3} \\ x = - \sqrt{3} \\ x1 = - \sqrt{3} \\ x2 = \sqrt{3} [/tex]
b)
[tex] |x - \sqrt{2} | = \sqrt{8} \\ |x - \sqrt{2} | = 2 \sqrt{2} \\ x - \sqrt{2} = 2 \sqrt{2} \\ x - \sqrt{2} = - 2 \sqrt{2} \\ x = 3 \sqrt{2} \\ x = - \sqrt{2} \\ x1 = - \sqrt{2} \\ x2 = 3 \sqrt{2} [/tex]
