Answer 1

Explicación paso a paso:

b)

$- \frac{1}{2} {x}^{3} {y}^{2} + 3{x}^{2} {z}^{2} \\ \\ = {x}^{2}(- \frac{1}{2}x {y}^{2} + 3{z}^{2})$

c)

${x}^{2} (y - 2) - y(x + 2) + 3 {y}^{3} \\ = {x}^{2}y - 2{x}^{2} - xy - 2y + 3{y}^{3}$

d)

$\frac{2}{3} {x}^{3}{y}^{2}z - 5{x}^{2}{y}^{3}{z}^{2} + 10 \\ = {x}^{2}{y}^{2}z(\frac{2}{3}x - 5y) + 10$
