Answer:
8a^3.
Step-by-step explanation:
(a+b)^3=a^3+b^3+3a^2b+3ab^2
(a-b)^3=a^3-b^3-3a^2b+3ab^2
(a+b)^3+(a-b)^3=2a^3+6ab^2
According to the question
(a+b)^3+(a-b)^3+6a(a^2-b^2)
Put in the value
=2a^3+6ab^2 +6a^3–6ab^2
=8a^3
X + y = 54
x - y = 34
----------------add
2x = 88
x = 88/2
x = 44
x + y = 54
44 + y = 54
y = 54 - 44
y = 10
so ur 2 numbers are 44 and 10
