Explicación paso a paso:
[tex]( a+3b)(a-3b) = 0[/tex]
[tex]( a+3b)(a-3b) =0, entoncas: (a)^{2} -(3b)^{2} =0[/tex]
[tex]a^{2} -9b^{2} =0[/tex]
[tex]a^{2} = 9b^{2}[/tex]
Dividimos por [tex]a^{2}[/tex].
[tex]\frac{a^{2} }{a^{2} } =\frac{9b^{2} }{a^{2} } ,entonces: 1 = \frac{9b^{2} }{a^{2} }[/tex]
Multiplicamos por tres(3).
[tex]3 ( 1 = \frac{9b^{2} }{a^{2} } ) ,entonces: 3 = \frac{27b^{2} }{a^{2} }[/tex]
[tex]Luego: \frac{27b^{2} }{a^{2} } = 3[/tex]
