Question

Please help me! Factor out the greatest common factor from the expression
-2x^2y^2z^2 – 8x^4yz^3 + 6x^3y^2z^3

Answer 1

All of them have xyz so you can factor out xyz to get xyz(-2xyz+8x^3z^2+6x^2yz^2) and all of that has at least x and z in it so you can go x^2yz^2(-2y+8x^2z+6y) and the highest coefficient that goes into that is 2 so your final answer should be 2x^2yz^2(-y+4x^2z+3y) I think, but it is very possible I made a mechanical error so double check just in case.
