That means find the constant term, the term without x. In binomial expansions, this is usually the term with (x to the power zero)
I'm not sure that I quite understand that. Surely with the binomial expansion shown above, all of the expanded terms world have an x somewhere.
Note: can be written as Just looking at the x terms (ignoring coefficients): The third term cancels out.
Hello, Rob! Don't argue about it . . . just expand it! Find the constant term in the expansion of . . . . . . . . . . . . . . .
