Answer 1

2(x^4 - 625)
2( (x^2)^2 - 25^2)
2( x^2 - 25)(x^2 + 25)
2(x+5)(X-5)(x^2 + 25)

Answer 2

so whats the answer?

Answer 3

the final ans is 2(x+5)(X-5)(x^2 + 25) as given above by ybarrap

Answer 4

Thanks can you help me with this on too ?
6b^4-17b^2-28

Answer 5

pls check if u hv typed it correctly.......

Answer 6

nope its right

Answer 7

let x = b^2
6b^4-17b^2-28
=6x^2 - 17x - 28
(6x + 7)(6x -24 )/6
=(6x + 7)6(x - 4)/6
=(6x + 7)(x -4)

substituting back:

(6b^2 + 7)(b^2 -4)
(6b^2 + 7)(b + 2)(b - 2)

Ans. (6b^2 + 7)(b+2)(b-2)
