I am trying to simplify (-4x?)(-2x?) does that work out to 8x? or just 8x?

8x^4 0 -
Its 8x4 (8 to the fourth) NO NEGATIVE
My notes from school say if your multiplying 2 negatives, it goes to positive. From my math teachers writeing.0 -

Yes. your right
Kayla: its -8x to the fourth.
so -8x4
The negatives cancel. The result is as you say, but positive.0 -

uhm. no -, just 8x^4, (-1)(-1) = 10 -
k, my mistake to, it was (-4x?)(-2x-?) 0 -

k, my mistake to, it was (-4x?)(-2x-?)
in this case it would be:
(-4x?)(-2x-?) = (-4)(-2)(x?)(x-?) = 8(x?)(x-?) = 8(x?-?) = 8x^0 = 8
or in other notation:
(-4x?)(-2x-?) = 8(x?)(1/x?) = 80 -
Man I don't miss school in the least bit!!! I will have math flashbacks for the rest of the night now though... 0 -

I know i realized what sbe did after i read it - i edited before your post :P0 -
First multiply the variables. Then to multiply exponents you add them. The exponents cancel out leaving 8 as the answer. 0 -
...uh, what EVERYBODY else said...their right...I checked 'em out...[:D]

it works out to 8X^4. (I don't know how to do superscripts)
2 negatives multiplied make a positive.0 -
