Factor the GCF: 2x4y2 − xy2 + 6x2y3 (10 points) xy2(2x3 − xy2 + 6x2y3)
xy2(2x3 − 1 + 6xy)
2xy2(x3 − 1 + 3xy)
2xy2(x3 − 1 + 4xy)

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
