Question

Factor this polynomial completely. If it will not factor, type PRIME.
x^2-x-20

Answer 1

x =-5x +4x
Not Prime for me

Answer 2

(x-5)(x+4)

Answer 3

-x = -5x +4x

Answer 4

so i guess a prime polynomial means it does not factor over the integers right?

Answer 5

because they all are factorable

Answer 6

(x-5)(x+4)?

Answer 7

yes thats right
i'm just understand what prime means

Answer 8

say we get a polynomial and it isn't factorable over the integers do we say its prime because all polynomials are factorable over the complex
and it doesn't which set of numbers we should be looking at
so i was just curious

Answer 9

yea i'm pretty sure it means you can factor it without having to use the complex number system

Answer 10

lol

Answer 11

am i wrong?

Answer 12

its says if it not factorable,then write prime
but all trinomials are factorable
i'm assuming they meant to say:
if is not factorable over the integers, write prime
