Solve logarithm Equation: log2 (12b - 21) - log2 (b^2 - 3)=2
Vikki [24]
Hn, well you should use the rule to answer this.. log_a(n)-log_a(m)=log_a (\frac{n}{m} )
Sorry if this doesn't seem to help, but here is the explanation: 
log_2 (\frac{12b-21}{b^2-3} )=2
\frac{12b-21}{b^2-3} =4
12b-21=4(b^4-3)
0=4b^2-12b-12+21
0=4b^2-12b+9&#10;
0=4b^2-6b-6b+9
0=2b(2b-3)-3(2b-3)
0=(2b-3)(2b-3)
b= \frac{3}{2}
Hn, so from this information we can determine that this solution does not work. And so forth your solution set shall indeed be: {x= 0}

I wish you good luck on your homework and hopefully I was somewhat beneficial to your needs. 

Best regards~ Sans
