# Math Help - Factor Polynomial

1. ## Factor Polynomial

Factor completely

9b2x - 16y - 16x + 9b2

I have no clue how to approach this.

Are you sure you have copied the problem correctly? If it were $9b^2x- 16y- 16x+ 9b^2y$ it would very straight forward.

9b^2(x + 1) - 16(x + y) is all you can do with THAT expression!
