c) 4a + 8b = 4 (∎)

d)xyz + yz + z = z (∎)

Answer 1

Copie substituindo os Quadrados e completando as fatorações

a)

bx + by = b (∎)

bx + by = b(x + y)

(∎)  = (x + y)

b)

ap + bp + cp = p (∎)

p(a + b + c)

(∎) (a + b + c)

c) 4a + 8b = 4 (∎)

4(a + 2b)

(∎)  = (a + 2b)

d)

xyz + yz + z = z (∎)

z(xy + y + 1)

(∎)  = (ay + y + 1)
