216w^3
You can separate it to 6w*6w*6w so then 6*6*6=216 and w*w*w=w^3
Multiply by 1/3 to reduce.
228*1/3=76m^2
216*1/3=72m^3
Multiply by 4 to increase.
228*4=912m^2
216*4=864m^3
I can explain more if you need.
(z-8) (z+2)
What I do to factor is find _x_=-16 and _+_=-6. -8x2=-16 and -8+2=-16. The coordinates for z if you were to graph this would be (8,0) and (-2,0)
see picture for the graph
equation: y = 1.50x
