x2-4=0
A.x = -1

B.x = 4

C.x = 2

D.x = 1

E.x = -4

F.x = -2

Answer 1

C and F

Explanation:

Answer 2

we are given

`x^2-4=0`

To find solution , we can factor it and then we can solve for x

step-1: Factoring

`x^2-4=0`

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

step-2: Solve for x

`(x-2)=0`

`x=2`

`(x+2)=0`

`x=-2`

so, option-C and option-F...........Answer
