Let the number be 'm' & 'n'
Hence
Product ; mn = 80
Sum ; m + n = 21
m = 21 - n
Substitute
(21 - n) n = 80
21n - n^2 = 80
n^2 - 21 n + 80 = 0 It is now in quadratic form to factor.
( n - 16)(n - 5) = 0
Hence the numbers are 5 & 16

Two numbers have a product of 80 their sum is 21?
Let the two numbers be x and y. According to question, x * y = 80.....................(1) and x + y = 21.................................................(2) (1) implies that y=80/x......................................(3) Now, Substituting this value in equation (2) we get, x + 80/x=21 or x2 - 21x + 80=0. Solving this quadratic equation x=16 and x=5. If x=16, then (3) implies y=5 If x=5, then (3) implies y=16. Hence the two numbers are 16 and 5.
