Answer:
n = 8
Step-by-step explanation:
Follow the question when turning the word equation into an equation
Because we know this is a quadratic equation, the product is a result of n multiplied by itself
[tex]n^{2} -4=60[/tex]
Solve for n
[tex]n^{2} =64[/tex]
[tex]\sqrt{n^{2} } =\sqrt{64}[/tex]
n = 8
