I need help solving this. The instructor asked us to expand the binomial
(x + delta x) raised to the power of 9.

My book has an explanation for differentiating but not what the prof wants.

Help! Thanks!
 
yep, I will. But, I am stumped by the "delta x", meaning the change in x.
 
Hello, bluebird!

If (x+Δx)9\displaystyle (x + \Delta x)^9 bothers you, expand (a+b)9\displaystyle (a + b)^9

. . then substitute x\displaystyle x for a\displaystyle a and Δx\displaystyle \Delta x for b.\displaystyle b.
