Question

what multiplied equals 25 but adds up to 24

Answer 1

Just exactly the way you wrote the question,
here's a pair of numbers that will do the job:

         22.9087  (rounded)
and
           1.0913  (rounded) .


If that  25  was actually supposed to be  -25 ,
then the two numbers would be

         25
and
         -1 .
