Question 492116
equation is:



14yz^3 + 28xy^2z – 7y^2z^2


if you factor out a 7 and a y and a z, then your expression becomes:


7yz * (2z^2 + 4xy - yz)


that looks like the greatest common factor.


no other factor is common to all 3 terms in the expression.


7yz * 2z^2 = 14yz^3 which is equal to the original first term.
7yz * 4xy = 28xy^2z which is equal to the original second term.
7yz * yz = 7y^2z^2 which is equal to the original third term.
