What are the coefficient rules when multiplying terms with variables?

Question

anonymous · Answer

example?

anonymous · Answer

There aren't example It's just a general question I guess

anonymous · Answer

hmm, if am thinking correctly, treat the coefficient the same as a variable. If they are the same combine/simplify it.

Thank you hun :)

If you are multiplying a lot of terms or several larger terms it might be worth having a look at the binomial theorem http://en.wikipedia.org/wiki/Binomial_theorem and the multinomial theorem http://en.wikipedia.org/wiki/Multinomial_theorem

lyrae · Answer

a lot of equal terms*

Multiply the numerical coefficients. (Do not confuse the numerical coefficients with the base.)
    Perform the multiplication on the variables:
        Keep the variables from each term.
        For each variable, add the exponents that appear for each variable. 

2zaxd • 3zcxb = (2 • 3)za + cxd + b + b =
6 za + cxd + b
