Answer:

There are two set of numbers

1)2.43,-16.43

2)-32.86,18.86

Step-by-step explanation:

Let assume these number as x and y.

then x+y=-14

 and x*y=-40

    ⇒[tex]x=\frac{40}{y}[/tex]

    [tex]\frac{40}{y}+y=14[/tex][tex]y^{2}+14y-40=0[/tex]

y =2.43 and -32.86

corresponding x =-16.43 and 18.86

2.43,-16.43

-32.86,18.86 [approximated upto two decimal places]
