Question

What are the solutions to m2 – 9 = 0? m = –9 and m = 0 m = –3 and m = 3 m = –3 m = 9

Answer 1

The answer is m = 3, -3

Answer 2

Answer:

m = 3 or m = –3

Step-by-step explanation:

Given,

$m^2-9=0$ -----(1)

For finding the solution of this equation we will solve it.

Adding 9 on both sides of equation (1),

$m^2 = 9$

$m= \pm \sqrt{9}$

$\implies m = \pm 3$

⇒ m = 3 or - 3

Thus, the solution of the given expression is m = 3 or m = -3.
