\"log%28%284x-7%29%29%2Blog%28%28x%5E2%2B4%29%29=0\", the base is \"a\".\r

\n" ); document.write( "You would want to simplify this and use Rational Roots Theorem if you want the SOLUTIONS for the equation. Could a value for x for which \"4x-7%3C0\" be acceptable in this equation? I believe not. You usually find logarithms of POSITIVE numbers of 0.
