Question

Factor.

8x2y2 – 4x2y – 12xy



4(8x2y2 – x – 12xy)


4(2xy – 4x2y – 12xy)


4x2y2(2xy – xy –3)


4xy(2xy – x – 3)

Answer 1

4xy[2xy - x - 3]

Explanation:

When finding the Greatest Common Factor [GCF], along with the coefficient, you have to factor out the least degree term possible, which in this case is 4xy. This is because although all terms have y and x, their degrees are not all similar, so we have to go with 4xy.
