h)mn-m+n-1
i)xao cubo+xao quadrado+2x+2
J)2ax+2bx+ay+by+az+bz

Answer 1

A- a(m+n)+b(m+n)= (a+b)(m+n)
B- z(xy+m)+3(xy+m)= (z+3)(xy+n)
C- 39p-13py= 13p(3-y)
D- 4(3m-n)+3p(3m-n)= (4+3p)(3m-n)
E- 4q(p+5)+x(p+5)= (4q+x)(p+5)
F- 2x²+3y² (os 6xy se anulam)
G- x(5y+3)+7(5y+3)= (x+7)(5y+3)
H- m(n-1)+n-1= (m+1)(n-1)
I- x²(x+1)+2(x+1)= (x²+2)(x+1)
J- 2x(a+b)+y(a+b)+z(a+b)= (2x+y+z)(a+b)
