You can put this solution on YOUR website!
log8(x^2-30)=log8(x)
\n" ); document.write( "x^2-30 = x
\n" ); document.write( "x^2-x-30 = 0
\n" ); document.write( "(x+5)(x-6) = 0
\n" ); document.write( "x = {-5, 6}
\n" ); document.write( "we can throw out the negative solution (extraneous) leaving:
\n" ); document.write( "x = 6 \n" ); document.write( "
