x^4-25x^2+5x-25

Answer 1

you can group terms toghther like this: (x^4-25x)+(5x-25)

Answer 2

x = 5

Answer 3

can you take out the common terms

and then I dont think we can factor it anymore. correct?

Answer 6

then we can do colect terms: (x-5)((x+5)(x^2+5))

Answer 7

Now that for sure isn't factorable anymore. Correct?
