Question 1038521
<font face="Times New Roman" size="+2">


Write out *[tex \LARGE f(x)\ =\ x^2\ -\ 3x^3] in pencil.  Then erase every *[tex \LARGE x] and replace each one with *[tex \LARGE (x\ +\ h)].  Then simplify the resulting expression.


The results of your first step should look like:


*[tex \LARGE f(x\ +\ h)\ =\ (x\ +\ h)^2\ -\ 3(x\ +\ h)^3]


Do the binomial expansions and then collect like terms.

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
