Question

a) 6x + 6y + ax + ay =
b) ax + ay + 7x + 7y=
c) 2a + 2n + ax +nx=
d) ax + 5bx + ay + 5by =
e) 3a – 3b + ax – bx =
f) 7ax – 7a + bx – b =
g) 2x – 2 + yx – y =
h) ax + a + bx + b =

Answer 1

a)6x+6y+ax+ay=
6(x+y)+a(x+y)=
(x+y)(6+a)

b)ax+ay+7x+7y=
a(x+y)+7(x+y)=
(x+y)(a+7)

Answer 2

Fatoração por agrupamento
a) 6(x+y) + a(x+y) = (x+y)(6+a)
b) a(x+y) + 7(x+y) = (x+y)(a+7)
