if x+y=10, and xy=16, what is (x-y)*(x^2 - y^2)?
with some logic we can figure out that
plug it in the equation,
\(360\) of course, there's the other way around where x is 2 and y is 8
i'll leave that to you!
"Other way around" is the same answer. Because here, you can consider absolute value since x and y are nonzero.
