Question

Alguem sabe a resposta????

Answer 1

a)

$\frac{4 {x}^{3} - {x}^{2} - 2x}{x} \\ = 4 {x}^{2} - x - 2$

b)

$\frac{5 {a}^{6} + 15 {a}^{3} - 10a}{5a} = {a}^{5} + 3 {a}^{2} - 2$

c)

$\frac{12 {x}^{5} - 8 {x}^{3} }{2 {x}^{2} } = 6 {x}^{3} - 4x$

d)

$\frac{2 {x}^{4} {y}^{4} - 4 {x}^{3}y }{2 {x}^{2}y } = {x}^{2} {y}^{3} - 2x$
