#1**+1 **

14 and 4 should do the trick !!!!

14 * 4 = 56

14 + 4 = 18

Mathematically, we have

xy = 56 → y = 56/x (1)

And x + y = 18 (2)

Sub (1) into (2) and we have

x + 56/x = 18 multiply through by x

x^2 + 56 = 18x subtract 18x from both sides

x^2 - 18x + 56 = 0 factor

(x - 14) (x - 4) = 0

Set both factors to 0 and solve for x and we have that x = 14 and x = 4

So either.......y = 56/x = 56/14 = 4 or y = 56/4 = 14

So......14 and 4 are the factors
