Question

Разложите на множители: ax+bx-ay-by+az+bz; ax-bx-x+ay-by-y;

Answer 1

а(х-у+z)+b(x-y+z)=(x-y+z)(a+b) ; x(a-b-1)+y(a-b-1)=(a-b-1)(x+y)

Answer 2

ax+bx-ay-by+az+bz=(ax+bx)+(-ay-by)+(az+bz)=x(a+b)-y(a+b)+z(a+b)=(a+b)(x-y+z); 

ax-bx-x+ay-by-y = (ax-bx-x)+(ay-by-y)=x(a-b-1)+y(a-b-1)=(a-b-a)(x+y)
