find all the numbers for which the rational expression is not defined on this problem 7 / 8v+9
\n" ); document.write( "-----
\n" ); document.write( "That fraction is undefined when the denominator is zero.
\n" ); document.write( "When is it zero?
\n" ); document.write( "8v+9 = 0
\n" ); document.write( "when 8v = -9
\n" ); document.write( "when v = -9/8
\n" ); document.write( "----------------------------
\n" ); document.write( "The expression is undefined when v = -9/8
\n" ); document.write( "===============================================
