x(5x^4+10x-8) or 5x^2(x^3+2)-8x
how did you get that answer
for the first one I factored out an x and see what's left for second one I noticed that first two terms(5x^5 & 10x^2) have common factor of 5x^2
okay so i need to find a common factor first
yes; always check to see if there is a common you can pull out
so the common is 5
5 doesnt really go into 8 that well; so look at the 'x's and see how many you can pull out
the lowest x is just x so is that the lowest
5x^5+10x^2-8x = x(5x^4 +10x -8) thats correct
I am really confused. so that is completely factored
since this is not in a usual form that we can see; we do a trial and error method to search for other factors
to make this faster; we can graph this on wolframalpha.com and see where the "roots" end up.
I don't see anything that is a common factor of 5,10, and 8
http://www.wolframalpha.com/input/?i=5x^5%2B10x^2+-8x this things a nightmare alright
your best bet is to take a stab at it; and if you get it wrong, just move along lol
do you have any answers to choose from ?
no I have to do it all on my own and show all my work
it looks to me like the answer you gave is as far as it can be factored
well; its as far as it can be neatly factored; so lets go with it :)
check ot for typos tho; make sure the question posted is the same as the one you want to find..... cause typos happen
teh happen to me alot lol
I hate this stuff
