Answer:

please mark brainlist

Step-by-step explanation:

Let the numbers be x and y

x = 3+y

x*y = 180

y = 180/x

x = 3 + 180/x

x^2 = 3x + 180

x^2 - 3x - 180 = 0

x^2 - 15x + 12x - 180 = 0

x (x-15) + 12 ( x-15) = 0

(x+12) (x-15) = 0

x=12. x=15

when x=-12, y=-12-3= -15

when x=15, y=12-3 = 12
