How would I do the problem (n to the power of two - 25)
n^2 - 25. Unless you are given a value for n or an equation of some sort there's nothing more you can do with these terms.
If you are supposed to factor:n^2 - 25 =(n - 5)(n + 5). ANSWERIf you are supposed to set it equal to 0 and solve:n^2 - 25 = 0(n + 5)(n - 5) = 0n+5 = 0 or n-5 = 0n=-5 or n=5. ANSWERS
