Question

раскрыть скобки(-5/2x-3/2y)^2

Answer 1

2*(-5:2х-3:2у)= -10:4х-6:2у

Answer 2

$( - \frac{5}{2} x - \frac{3}{2} y) ^{2} \\ ( - \frac{5}{2} x)^{2} - 2 \times ( - \frac{5}{2} )x \times \frac{3}{2} y \times ( \frac{3}{2} y)^{2} \\ \frac{25}{4} x ^{2} + \frac{15}{2} xy + \frac{9}{4} {y}^{2}$
