Question

1) Fatore as expressões:

Observe o modelo:
2a – 2m + 2n = (R: 2 (a -m+n))

a) 6x + 6y + ax + ay =
b) ax + ay + 7x + 7y=
c) 2a + 2n + ax +nx=

2) Efetue as adições algébricas:
a) 3 x y - 11 x y + 4 x y
b) - y + 3 y - 2y-y

Answer 1

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

6(x+y)+a(x+y)

(6+a)(x+y)

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

a(x+y)+7(x+y)

(a+7)(x+y)

c) 2a + 2n + ax +nx=

2(a+n)+x(a+n)

(2+x)(a+n)

2) a) 3 x y - 11 x y + 4 x y = -4xy

b) - y + 3 y - 2y-y = -y
