Does this problem let usage of a calculator? Because I used a calculator to discover that the factors of 1441 are 131 and 11.


*To check if a number is prime


So knowing that 131 and 11 multiply to 1441, we can see that miraculously if you substitute 1 for n in your equation 60+ k * 71n you get 131*k. And since 11 multiplied by 131 is 1441, k should be \(\boxed{11}\).

What I would do is use the quadratic formula.


Then add the squares of the roots. You would get a real number.


Here is practice for complex solutions to quadratics if you are having trouble on these types
