Question

Olá galera queria que vcs me respondessem 3 questões
A)2wy - 2xy + wz - xz

B)wx - xy + 2wz - 2yz

C)2m² n² - 4mn

Answer 1

A)2wy - 2xy + wz - xz ==> 2y(w - x) + z(w - x) ==> (w - x )(2y + z)

B)wx - xy + 2wz - 2yz ==> x(w - y) + 2z(w - y) ==> (w - y )(x + 2z)

C)2m² n² - 4mn ==> 2mn(mn - 2)

Answer 2

a) 2y(w-x)+z(w-x)=
 (2y+z)(w-x)

b) x(w-y+2z((w-y)=
    (x+2z)(w-y)

c) 2mn(mn)-4(mn)=
  (2mn-4)(mn)
