ОДЗ: t + 2 ≠ 0, t ≠ -2
t - 3 ≠ 0, t ≠ 3

$2 {t}^{2} - 5t + 2 = 0 \\ d = {b}^{2} - 4ac = 25 - 4 \times 2 \times 2 = 25 - 16 = 9 \\ t1 = \frac{5 + 3}{2 \times 2} = \frac{8}{4} = 2 \\ t2 = \frac{5 - 3}{2 \times 2} = \frac{2}{4} = \frac{1}{2}$
${2}^{x} = 2 \\ x = 1 \\ \\ {2}^{x} = \frac{1}{2} \\ {2}^{x} = {2}^{ - 1} \\ x = - 1$
