Answer:
ill answer in a minute
Step-by-step explanation:
Let the number be n. Then
n^2 - (n/2)^2 = 108.
n
From this we get n^2 - (---- )^2 = 108.
2
Mult. both terms by 4, with the result 4n^2 - n^2 = 432
Then 3n^2 = 432, and n^2 = 144. n could be either 12 or -12. You must check both answers by subst. them into the original equation.
