To find the solutions for the equation m2 – 9 = 0, we can start by factoring it. This equation can be factored as:
(m – 3)(m + 3) = 0
Setting each factor equal to zero gives us two possible solutions:
- m – 3 = 0 ⟹ m = 3
- m + 3 = 0 ⟹ m = -3
Thus, the solutions to the equation are m = 3 and m = -3.
