What are the solutions of the equation 2x2 = 2? Use a graph of the related function.
A function means a correspondence from one value x of the first set to another value y of the second set.
Answer: x = -1 or x = 1
Let's look at the explanation to understand it better.
2x2 = 2 is the equation we've been given.
Let's start by dividing both sides of our equation by 2.
⇒ 2x2 / 2 = 2 / 2
⇒ x2 = 1
Using the square root of both sides of our equation, we get
⇒ |x| = 1
⇒ x = ±1
x = -1 or x = 1
