Answer:
2 and 6
Step-by-step explanation:
Take integers to be X and Y
X*Y=12
X + Y = 8
from the second equation, X= 8-Y
put X in the first Equation
(8-Y)Y = 12
Expand the equation
-Y² + 8Y - 12 = 0
Factorize the above equation
(-Y + 2) (Y - 6) = 0
Y = 2 and Y = 6
choose any value of Y.
so Y = 6,
put Y in X + Y = 8
X + 6 = 8
X = 2
therefore the integers are 2 and 6
