Question

Solve the equation c²=4

Answer 1

c = 2, c = -2

Explanation:

The question is asking us to solve the equation
`\sf{c^2=4}`.

To solve it, we take the square root of each side. Note that once we do this, we will have 2 solutions.

`\sf{√(c^2)=√(4)}`

`\sf{c=2,c=-2}`

Therefore, this equation has two solutions, which are c = 2 and c = -2.

Answer 2

c^2 =4 the square root of four is 2 so two is your answer
