Question

Fatore,utilizando a fatoração por agrupamento

a)xy-x-y+1
b)5a+5b+5c-ax-bx-cx
c)x^6+x^5+x^4+x^3
d)4xy+6y+10x+15
e)4m^2-6m+2my-3y
f)ac^2+bc-ad^2-bd^2
g)5xy+15xm+3zy+zm
h)ax-ay-bx+by

Answer 1

a)x.(y-1)-1.(y-1)=(x-1).(y-1)
b)5.(a+b+c)-x(a-b-c)=(5-x).(a+b+c)
c)x^(6+5+4+3)
d)2y(2x+3)+5(2x+3)=(y+5).(2x+3)
e)2m(2m-3)+y(2m-3)=(2m+y).(2m-3)
f)c^2(a+b)-d^2(a-b)=(c^2-d^2).(a-b)
g)5x(y+3m)+z(y+3m)=(5x+3z).(y+3m)
h)a(x-y)-b(x+y)=(a-b)-(x-y)
