Answer:
m = 3 or m = –3
Step-by-step explanation:
Given,
[tex]m^2-9=0[/tex] -----(1)
For finding the solution of this equation we will solve it.
Adding 9 on both sides of equation (1),
[tex]m^2 = 9[/tex]
[tex]m= \pm \sqrt{9}[/tex]
[tex]\implies m = \pm 3[/tex]
⇒ m = 3 or - 3
Thus, the solution of the given expression is m = 3 or m = -3.
