Question

can anyone help??
Factorise x2 − 5

Answer 1

a2-b2=(a-b)(a+b)
Well I guess you got confused as 5 isn’t a perfect square
Take 5 as rt5 square
Thus it becomes (x-rt5)(x+rt5)
There ya go

Answer 2

Answer:

(x+$\sqrt{5\\}$)(x-$\sqrt{5}$)

Step-by-step explanation:

The given expression is in the form of  $x^{2}$-$y^{2}$

Therefore on factorizing, we will get,

(x+$\sqrt{5\\}$)(x-$\sqrt{5}$)
