Question

factor 5x^5+10x^2-8x

Answer 1

x(5x^4+10x-8)
or
5x^2(x^3+2)-8x

Answer 2

how did you get that answer

Answer 3

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

Answer 4

okay so i need to find a common factor first

Answer 5

yes; always check to see if there is a common you can pull out

Answer 6

so the common is 5

Answer 7

5 doesnt really go into 8 that well; so look at the 'x's and see how many you can pull out

Answer 8

the lowest x is just x so is that the lowest

Answer 9

5x^5+10x^2-8x = x(5x^4 +10x -8) thats correct

Answer 10

I am really confused. so that is completely factored

Answer 11

since this is not in a usual form that we can see; we do a trial and error method to search for other factors

Answer 12

to make this faster; we can graph this on wolframalpha.com and see where the "roots" end up.

Answer 13

I don't see anything that is a common factor of 5,10, and 8

Answer 14

http://www.wolframalpha.com/input/?i=5x^5%2B10x^2+-8x this things a nightmare alright

Answer 15

lol

Answer 16

your best bet is to take a stab at it; and if you get it wrong, just move along lol

Answer 17

do you have any answers to choose from ?

Answer 18

no I have to do it all on my own and show all my work

Answer 19

it looks to me like the answer you gave is as far as it can be factored

Answer 20

well; its as far as it can be neatly factored; so lets go with it :)

Answer 21
