factorise the following x^5- 16x​

Answer 1

Answer:

not so hard try it urself

Answer 2

Step-by-step explanation:

$x {}^{5} - 16x \\ = x(x {}^{4} - 16) \\ = x(x {}^{2} ) {}^{2} - (2 {}^{2} ) {}^{2} \\ = x(x {}^{2} - 4)(x {}^{2} + 4) \\ = x(x - 2)(x + 2)(x {}^{2} + 4)$

hence x, (x-2), (x+2), (x^2+4) are the factors..
