Question

(Squreroot x+2)(squreoot x-2)=0

Answer 1

`\boxed{ \ x = 2 \ or \ x = -2 \ }`

Explanation:

I understand that you want to solve this equation

`√(x+2)√(x-2)=0`

<=>

`√((x+2)(x-2))=0`

<=>

`(x+2)(x-2)=0`

<=>

x = 2 or x = -2

hope this helps

if your question is
`(√(x)+2)(√(x)-2) = 0`

then this is
`(√(x))^2-4 = 0\\<=> x = 4`
