This is for a quiz if anybody could factor this that would be a great help. Thanks! +kkkk

Factor (x-5)(x^2+x+2)
 
The first term is already factored so you could just factor an x out of the 2nd part which would give youe x(x-5)(x+2)
 
wait fuck me i thought it was (x^2+2x) forget what i said you can't factor an x out because theres a 2 in there
 
this thread is full of fail.

and that kid is right you can't factor it. if you plug it into a calculator, there is only one root, so you can't possibly factor it more. I tried reducing by using 5 as a root and came out with an imaginary number.

Unfortunately there are no asians on ns.
 
He said factor, not multiply them together.

If your looking for answers, depending on the context of the question, you could solve (x-5) and (x^2+2+2) separately for 0 which would give you 5 and a nonreal answer since you get 1 +- root(1-8) / 2

So it would be 1+-i(7^1/2)/2
 
I used the quadratic equation in case you were wondering. And if you don't know i = square root of -1 which is an imaginary number
 
Ok wouldn't the first half be x=5 and then you would plug in the x^2+x+2 into the quadratic formula , then set those factors equal to zero and solve. Then check for extraneous roots? That's how we do it at school I think.
 
The first term would make x=-5, and the other one you have to use the quadratic formula to figure it out, which then would be your second term, and if you completely simplified it, it would be an imaginary number. but if you haven't learned about them yet, I would just write it out like I have it (while taking into account that I'm typing it out, so it looks a little weird haha)

x= 5, (-1±√(-7))/2
