Hey there!

ANSWER:
c=2 \text{ or } c=-2

Step-by-step explanation:


c^2=4

If you are looking to find c, let's see what types 2 equals for.


c*2=4

We know a number * 2 = 4. That number is 2. Let's see if c is equal to 2.


c*2=4\\2*2=4

The answer is true because 2 * 2 does equal 4. So the answer is
c=2.


c=2

But the value can be a negative as well because
2^2 is also equal to 4.


c^2=4\\-2^2=4\\c=-2

Hope this helps!
