Question

How do i solve n squared - 62

Answer 1

The rule for this one is called the difference of squares
A^2 - b ^2 = (a+b)(a-b)

Using this rule
N^2 - 62 = (n+ sqrt(62)) (n - sqrt(62))

The solution for this one is to make the statement = 0
0 = (n+ sqrt(62)) (n - sqrt(62))

N can either be +- sqrt(62)
