How many solutions are there to the equation x^2 = 1? explain how you know.

Two solutions

Step-by-step explanation:

Let's clear the variable x.

Since x is squared we apply square root to clear

We have the following term

This term corresponds to the formula of a absolute value of a number.

The absolute value of a number is its distance from zero on a number line

the absolute value of x is equal to 1 this means that x takes all the values that are at a distance of one unit from zero on the real line

The numbers that have a distance of 1 unit from zero would be 1 and also -1 (as it is a distance the module is always positive)

step-by-step explanation:

infinity is the answer
