432(140-x)^3 = 60480-432x^3

or do i have to expand it like this

432(140-x)(140-x)(140-x)

**Reiny**, Tuesday, June 22, 2010 at 7:05pmYou will have to expand it, your first line is incorrect.

test it with numbers...

e.g.

3(2^3) = 3(2)(2)(2) = 3(8) = 24

the way you wanted to do it would be

(6)^3 or 216
