find the value of A and B if
sqrt(A) x sqrt(B) = 4
sqrt(A) - sqrt(B) = sqrt(8)
----
Note: sqrt(A) = sqrt(B)+sqrt(8)
----
Substitute for sqrt(A) and solve for B.
(sqrt(B)+sqrt(8)(sqrt(B)) = 4
B + sqrt(8B) = 4
(sqrt(B))^2 + sqrt(8)*sqrt(B) - 4 = 0
----
Use the Quardratic Formula to solve for sqrt(B)
Then solve for B
Then solve for A
