Question

What is the square root of 4x^2-16=0

Answer 1

Explanation:

The only way I think to answer this (although I gotta say it's worded kind of strangely) is to factor it. If

`4x^2-16=0` then

`4x^2=16` and

`x^2=4`

That means that, taking the square root of both sides, gives you that

x = ±2

Answer 2

2

Explanation:

4x^2=16

Divide both sides by 4.

x^2=4

x=2
