Question

How to factor the polynomial x^4-100 and graph it

Answer 1

I know it goes up on both sides

Answer 2

also, the degree is 4, so it would have 3 turns

Answer 3

you can factorise it by noticing this is the difference of 2 ssquares

Answer 4

idk

Answer 5

how would you do that with x^4 though and not just x^2

Answer 6

(x^2 -a^2) = (x+a)(x-a). So in this case we have (x^2)^2 and 10^2. ok?

Answer 7

ah

Answer 8

well what do I do with that???

Answer 9

I need to graph it

Answer 10

so have ((x^2)^2 - 10^2) which is (x^2-10)(x^2+10)

Answer 11

yh?

Answer 12

ok I have it now thx man
