Question

What is the solution to the equation mc026-1.jpg?
n = –4, n = –1
n = –1
n = 1
n = 1, n = 4

Answer 1

I can’t see the image file mc026-1.jpg. Could you either paste the equation here or describe it?

If it’s a quadratic, here are the common possibilities that match the answer choices and how they come about:

- n^2 + 5n + 4 = 0 factors as (n + 1)(n + 4) = 0 → n = −1, −4.
- n^2 + 2n + 1 = 0 factors as (n + 1)^2 = 0 → n = −1 (double root).
- n^2 − 2n + 1 = 0 factors as (n − 1)^2 = 0 → n = 1 (double root).
- n^2 − 5n + 4 = 0 factors as (n − 1)(n − 4) = 0 → n = 1, 4.

If you paste the equation I’ll solve it and pick the correct choice.
