How possible is x^2+xy+xz+z be grouped and factor out, iv been trying but there seem no

common binomial n the expression. Please guide me on this. Thank you

when i tried to solve it it became:

x(x+y) + z(x+1) ... i could not see the common here - July 5th 2012, 11:41 PMProve ItRe: factor by grouping
I don't think it factorises...

Yes it can be solved when x^2 + xy +xz +yz=x(x+y)+z(x+y)

= (x+y)(x+z).
