There are not two INTEGERS that can add to make 9 and multiply to make 4, however there are some Irrational Numbers that will do the job.
Let x and y be the two numbers.
x + y = 9
xy = 4 so y = 4/x
x + 4/x = 9
x² + 4 = 9x
x² - 9x + 4 = 0
using the quadratic formula,
x = (9 ± √[81-4(1)(4)])/2 = (9 ± √{81-16])/2 = (9 ±√65)/2
≈ 8.531129 or 0.468871
So the two numbers are approximately 0.468871 and 8.531129
