Factor out the greatest common factor from the expression
14yz3 + 28xy2z – 7y2z2

You can put this solution on YOUR website!
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.
