Question

What are the solution(s) of x2-4-0? X= 4 or X=4 X=-2 or x= 2 x=2 x=4

Answer 1

Answer:

Step-by-step explanation:

First you add 4 on both sides

X^2=0

Then you take square on both sides

X=+- the square root of 4

Simplify that

X=plus or minus 2

The answer can be either -2 or +2 (which is just 2)
