Step-by-step explanation:
Hey, there !!
Let's simply work with it,...................
Here, theequation is,
[tex] {m }^{2} - 4 = 0 [/tex]
[tex]or \: {m }^{2} = 4[/tex]
[tex]or \: m = + - \sqrt{4} [/tex]
[tex]or \: m = + - \sqrt{ {2}^{2} } [/tex]
cancelling square and square root we get answer is,
= (+ - 2).
It means the value of m is plus(+) minus(-) 2.
Hope it helps...
