Question

What are the solutions to m2 - 9 = 0?

Om = -9 and m = 0
Om = -3 and m = 3
0 m = -3
Om = 9

Answer 1

Given:

`m^2-9=0`

Let's find the solutions to the given equation.

Add 9 to both sides of the equation:

`\begin{gathered} m^2-9+9=0+9 \\ \\ m^2=9 \end{gathered}`

Take the square root of both sides:

`\begin{gathered} \sqrt[]{m^2}=\pm\sqrt[]{9} \\ \\ m=\pm3 \\ \\ m=-3\text{ and m=3} \end{gathered}`

Therefore, the solutions to the equation are:

m = -3 and m = 3

ANSWER:

m = -3 and m = 3
