Fatore os polinomios

A) 5x - xy + 15 - 3y

B) am + bm + an + bn

C) 2bc + 5c - 10b -25c

D) hx - 2x + 5h - 10

E) 3a - 6y + ab - 2by

Answer 1

A) 5x - xy + 15 - 3y =
    x(5x -y) + 3(5 - y)

B) am + bm + an + bn =
     m(a +b) + n (a +b)

C) 2bc + 5c - 10b -25c =
     c(2b +5) - 5(2b - 5)

D) hx - 2x + 5h - 10 =
     x(h -2) + 5(h -2)

E) 3a - 6y + ab - 2by =
     3(a -2y) + b(a -2y)
