So my problem is converting

16(2t-8)^7 * (t+5 ) - (2t-8)^8 to 256(t-4)^7 * (7t+44)

So I'd bring out (2t-8)^7 and have

(2t-8)^7 * (16(t+5) - (2t-8))

working in the right side it'd be 16t+80-2t+8 or (2t-8)^7(14t+88)...can bring out a 2, so (2t-8)^7*2(7t+44)

Doesn't explain that 256 to me yet, am I still on the right track or did I muck up in my algebra again?
