[tex]\sf Hello![/tex]

[tex]\sf m^{2} - 9 = 0[/tex]

⇒ [tex]\sf m^{2} = 9[/tex]

⇒ [tex]\sf m[/tex] = ± [tex]\sqrt{\sf 9}[/tex]

⇒ [tex]\sf m[/tex] = ± [tex]\sf 3[/tex]

⇒ [tex]\sf m = 3 \:\: or \:\: m = -3[/tex]

[tex]\sf Hence,[/tex]

[tex]\sf The\: solutions\: for \:the \:eqn.\: \sf m^{2} - 9 = 0\: is[/tex] ± [tex]\sf 3[/tex]
