# Hi i dont know how to multiply my fractions with exponents and variables

Im in pre algebra and i have no clue please help meh!!

You're multiplying fractions, like any fractions. The Top time the Top over the Bottom time the Bottom.

As for the variables and exponents, you're only multiplying polynomials.

Eample

• ((x2 - 1x - 6)/7x) * ((x+2)2/(4X-2))
• ( (x2 - 1x - 6) * (x+2)2 ) / ( 7x * (4x -2) )   Multiply fractions
• ( (x - 3)(x+2) * (x+2)(x+2) ) / ( 28x2 - 14x )  Factored the numerator, multiplied the denominator
• ( (x-3)(x+2)3 ) / ( 28x2 -14x )  Was able to recombine the numerator

Clearly there would be a few different ways you could represent this, but it's an example.
If you have specific questions feel free to ask.

Hopes this helped a bit,

Hi Angela,

We can probably help you a lot better if you give us a few samples of the problems you are working on.  There are a lot of ways to work out fraction multiplications with exponents and variables.  Can you type up two or three examples?  In the meantime, you may find this website useful: http://www.onemathematicalcat.org/algebra_book/online_problems/md_frac_var.htm

If you send along some samples, I'm sure we can help you out!
