Question

Agrupe os termos que possuem fator comum e fatore as expressões:
a)2x+xz+2y+yz=
b)10a-15+4ab-6b=
c)ac+c²+ay+cy=
d)14z-28+6xz-12x=
e)a²+ba+2a+2b=

Answer 1

a) x (2+z) + y (2+z)
(2+z) (x+y)
b) 5 (2a-3) + 2b ( 2a-3)
(2a-3) (5+2b)
c) c (a+c) + y (a+c)
(a+c) (c+y)
d) 14 (z-2) + 6x (z-2)
2 (z-2) (7+3x)
e) a (a+2) + b (a+2)
(a+2)( a+b)
