Question 965209
{{{log((x+4))+log((x-3))=1}}}
{{{log((x+4)(x-3))=1}}}
{{{x^2+x-12=10}}}
{{{x^2+x-22=0}}}
{{{x^2+x+1/4-22=1/4}}}
{{{(x+1/2)^2=88/4+1/4}}}
{{{(x+1/2)^2=89/4}}}
{{{x+1/2=0 +- sqrt(89)/2}}}
{{{x=-1/2 +- sqrt(89/2)}}}
Since only positive arguments are allowed for the log function.
{{{highlight(x=(sqrt(89)-1)/2)}}}
