Algebra.Com's Answer #185915 by drk(1908)![]() ![]() ![]() You can put this solution on YOUR website! We have 2 zeros at 2 and 2. \n" ); document.write( "The third zero is \n" ); document.write( " \n" ); document.write( "The fourth zero is the conjugat of this which is \n" ); document.write( " \n" ); document.write( "Remember: imaginaries always occur in pairs. \n" ); document.write( "So, we have \n" ); document.write( " \n" ); document.write( "The product of these factors is \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "But we wanted 32 as the constant, so multiply by 4 to get \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
