Question

(xy+yz-xy)-(2xy+2yz)-(xz-xy-zy)

Answer 1

Resposta:

(xy+yz-xz)-(2xy+2yz-2zx)-(xz-xy-zy)

xy + yz - xz - 2xy - 2yz + 2xz - xz + xy + yz

2xy - 2xy + 2yz - 2yz - 2xz + 2xz

0

Explicação passo-a-passo:

Answer 2

(xy+yz-xy)-(2xy+2yz)-(xz-xy-zy)

((xy - xy)+yz) - (2xy+2yz) - (xz - xy - zy)

yz - (2xy+2yz) - (xz - xy - zy)

yz - 2xy - 2yz - xz+xy+zy

(yz - 2yz+yz)+(-2xy+xy) - xz

-xy - xz
