Answer 1

Answer:

$\huge\boxed{\fcolorbox{blue}{orange}{HELLO\:MATE}}$

Step-by-step explanation:

GIVEN :

$x^{3}-5x^{2}-x-5$

TO FIND:

To factorise the given expression.

SOLUTION:

=$x^{3}-5x^{2}-x-5$

=$x^{2}(x-5) -1(x+5)$

=$(x^{2}-1) (x+5)$

$\large\red{\boxed{a^{2}-b^{2}=(a+b) (a-b)}}$

=$(x+1) (x-1) (x+5)$

$\large\purple{\boxed{ANSWER:(x+1) (x-1) (x+5)}}$
