Factoring a Polynomial

Question

I need help understanding how to factor the following polynomial:

x^4-36

Can someone explain? Thanks.

Answer 1

this is to use the formula a^2 - b^2 = (a+b)(a-b)

in this case, x^4 - 36 = (x^2 + 6) (x^2 - 6)

Answer 2

(7a^2b+7ab^2)+(6ab^2-7a^2+b)

Answer 3

thats not a polynomial. if that was squared, eg. (x^4-36)^2

than it would factor out.

Answer 4

(x - ¼)²

Answer 5

(X+Y)(X-Y) is the formla (x^2+6)(x^2-6)

Answer 6

it is 50

Answer 7

I think that is it 70k

Answer 8

r^2-16w+4wr-4tr

Answer 9

x+y-4=0
