Solve for m.

Question

m2 − 4 = 0

Write your answers as integers or as proper or improper fractions in simplest form.

m =
or m =

Answer 1

To solve the equation \( m^2 - 4 = 0 \), we can start by adding 4 to both sides:

\[ m^2 = 4 \]

Next, we take the square root of both sides. Remember that taking the square root introduces both a positive and a negative solution:

\[ m = \pm \sqrt{4} \]

Since \( \sqrt{4} = 2 \), we have:

\[ m = 2 \quad \text{or} \quad m = -2 \]

Thus, the solutions are:

\[ m = 2 \quad \text{or} \quad m = -2 \]
