Question

What is the solution of 2x^2=8

Answer 1

x = 2

Explanation:

So I'm assuming you are wanting to solve for x

So first we have to take the square root of both sides

`\sqrt{2x^(2) }` =
`√(8)`

So the equation now looks like

2x =
`√(8)`

Now we divide by two on both sides to isolate the x

So now our equation looks like

x =
`\sqrt{(8)/(2) }`

We can simplify
`\sqrt{(8)/(2) }` because that equals 2

So now we have x = 2

Answer 2

2

Explanation:

2x^2=8

2x^2/2 = 8/2

x^2=4

x=2
