Answer: 27 and 125
Step-by-step explanation:
Let the two numbers be x and y
Sum of numbers = 8
x+y = 8
x = 8-y
Product of numbers = 15
xy = 15
y(8-y) = 15
8y - y² = 15
y² - 8y + 15 =0
y² - 5y -3y +15 =0
y(y-5) -3(y-5) = 0
(y-5)(y-3) = 0
y = 5 or y = 3
If y = 5 then x = 3
If y = 3 then x = 5
the two numbers are 3 and 5
Their cubes are 27 and 125
