Steps for factoring 15cw-20cz-6dw+8dz

You have to factor by grouping. so break it down and find the gcf between 15 and 20 and then find the gcf between 6 and 8 so you should get - 5c (-3w+4z) 2d (-3w+4z) and your final answer should be (-5c+2d) (-3w+4z)

Add the common like terms but first seperate them and the pair them
