(\frac{3}{4} - \frac{5}{2})^{2} - (\frac{3}{4})^{2}

(\frac{3}{4} - \frac{5}{2})^{2} = \frac{49}{16}

(\frac{3}{4})^{2} = \frac{9}{16}

= \frac{49}{16} - \frac{9}{16}

\frac{49}{16} - \frac{9}{16} = \frac{5}{2}

= \frac{5}{2}

2 (x - 1)^{2} + 7 = 39

(x - 7)^{2} + 4 = 0

- 4 x - 32 < 4

∣ x - 2 ∣ < 7
