solve for x:
\n" ); document.write( "log2(x+2) + log2(x+6)=5
\n" ); document.write( "log2[(x+2)(x+6)]=5
\n" ); document.write( "convert to exponential form: base(2) raised to log of number(5)=number(x+2)(x+6)
\n" ); document.write( "2^5=x^2+8x+12
\n" ); document.write( "32=x^2+8x+12
\n" ); document.write( "x^2+8x-20=0
\n" ); document.write( "(x+10)(x-2)=0
\n" ); document.write( "x=-10(reject, x>0)
\n" ); document.write( "or
\n" ); document.write( "x=2
\n" ); document.write( "
\n" );
