se puderem me ajudar a fatorar, agradeço​​

Answer 1

Resposta

j) am-m+an-n

m(a-1)+n(a-1)

(a-1)(m+n)

-------------------

k) x^2y+xz+y+z

x^2y+y+xz+z

xy(x+1)+z(x+1)

(x+1)(xy+z)

------------------------

l) 3kp-5p-21k+35

p(3k-5)-7(3k-5)

(3k-5)(p-7)

---------------------

m) ax-2bx +ay-2by-3a+6b

x(a-2b)+y(a-2b)-3(a-2b)

(a-2b)(x+y-3)

--------------------------

n) 7ab+b -2-14a

7ab+b -14a-2

b(7a +1) -2(7a+1)

(7a+1)(b-1)

------------------------

o) 6ab^2-ac -cd +6b^2d

6ab^2-ac +6b^2d-cd

a(6b^2-c) +d(6b^2-c)

(6b^2-c)(a+d)
