help
i have denominator
so after factoring and applying the multiplications I get: (x-4)(x+2) / [x(x+2)(x-2)] + 4(x) / [x(x+2)(x-2)]
so then I just add my numerators to get (x-4)(x+2) + 4x ^ now you can start expanding that
can you try doing the entire expansion in one comment ^^ it's a little less confusing that way
x^2 -8x 2x
you're forgetting about the constant term ^^"
remember foil
(x-4)(x+2) = x^2 + 2x - 4x - 8 = x^2 - 2x - 8
then we just add + 4x to get x^2 + 2x - 8 as the numerator
this expression factors out to get (x+4)(x-2) [not the same as the original, the signs are switched]
x^2-2x-8/x^2+2 is answer
x^2 + 2 is not the denominator
[x(x+2)(x-2)] ^ this is the denominator
oh ok
thank you for your help
then we write this out to get (x+4)(x-2) / [x(x+2)(x-2)] notice anything you can cancel out?
there's more lol
x-2
good, now we get (x+4)/ [ x * (x+2) ] as our answer
so that's the finl answer
remember, you can use mathway to check your answers but your teacher is expecting all of the steps I have shown you
that's it
anyway I gotta go study for finals, good work today and take care
