The equation given is m² – 9 = 0, which is a quadratic equation. To find the solutions, we can start by rearranging the equation.
First, we can add 9 to both sides of the equation:
m² = 9
Next, to solve for m, we can take the square root of both sides:
m = ±√9
This simplifies to:
m = ±3
Therefore, the solutions to the equation are:
- m = 3
- m = -3
In summary, the solutions to m² – 9 = 0 are m = 3 and m = -3.
