Question

Fatore a expressão, simplifique-a e calcule seu valor numérico

Answer 1

Resposta passo a passo:

$\frac{(zx^{2}+ y^{2}z+2xyz ).(x^{2} -y^{2} )}{x^{3} +3x^{2} y+3xy^{2}+y^{3} }$

$\frac{z.(x^{2}+ y^{2}+2xy ).(x^{2} -y^{2} )}{x^{3} +3x^{2} y+3xy^{2}+y^{3} }$

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

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

$\frac{z.(x+y)^{3} .(x-y)}{(x+y)^{3} }$

$z.(x-y)$

$0,25.(0,75-(-1,25))$

$0,25.(0,75+1,25)$

$0,25 .(2)$

$0,5$
