$⟹</p><p>(5 - 2x)(3 + x)$

$⟹</p><p>5(3 + x) - 2x(3 + x)$

$⟹</p><p>15 + 5x - 6x - 2 {x}^{2}$

$⟹</p><p> - 2 {x}^{2} - x + 15 = 0$

$⟹</p><p> - (2 {x}^{2} + x - 15) = 0$

$⟹</p><p>2 {x}^{2} + 6x - 5x - 15 = 0$

$⟹</p><p>2x(x + 3) - 5(x + 3) = 0$

$⟹</p><p>(2x - 5)(x + 3) = 0$

$⟹</p><p>2x - 5 = 0 \: \: | \: x + 3 = 0$

$⟹</p><p>[tex]{\boxed{x = \frac{5}{2} \: | \: x = - 3}}$
