The first step to solving this is to split the equation into the possible cases. when the product of factors equals 0, at least one of these factors is 0. n - 1 = 0 n + 6 = 0 n + 5 = 0 now you need the equations for n n = 1 n = -6 n = -5 this tells us that the final solutions are the following: n = -6, n = -5, n = 1 1 2 3 let me know if you have any further questions :)
Explanation: To solve the equation means to get the values of n which satisfy the given equation. The equation given is: (n-1) (n+6) (n+5) = 0 This equation will be true if any of the terms (brackets) is equal to zero. This means that: either n-1 = 0 .............> n = 1 or n + 6 = 0 ................> n = -6 or n + 5 = 0 ................> n = -5
