We can let the numbers be x and y.
then
x + y= 14 and xy = 45
Since x= 14 - y
we can substitute 14- y in the equation xy= 45
(14-y)y= 45
14y - y^2= 45
-y^2 +14y -45 =0
let common ( -) minus
y^2 -14y +45=0
y^2 -9y-5y +45 =0
y(y-9) -5(y-9)=0
(y-5) (y-9) =0
y =>5,9
so y =5 put in the equation
X = 14-5 =9
X =9 , y = 5
& the difference between
9-5 = 4
