Question

What are the solutions of the equation 2x2=2 use a graph of the related function

Answer 1

`x=-1\text{ or }x=1`

Explanation:

We have been given an equation
`2x^2=2`. We are asked to find the solutions of our given equation.

First of all, let us divide both sides of our equation by 2.

`(2x^2)/(2)=(2)/(2)`

`x^2=1`

Upon taking square root of both sides of our equation we will get,

`x=√(1)`

`x=\pm 1`

`x=-1\text{ or }x=1`

Therefore,
`x=-1\text{ or }x=1` are two solutions for our given function.

Answer 2

The equation given is
2x² = 2
x² = 1
x = √1
x = 1

The solution is both -1 and 1 and the graph is shown below
