In the given above, we have an equation that is equal to,
x² + bx - c = (x + m)(x - n)
If we are to apply distributive property on the items at the right hand side of the equation, the equation becomes,
x² + bx - c = x² - nx + mx - mn
Simplifying,
x² + bx - c = x² + (m-n)x - mn
If b is a positive number, m-n should be positive. Therefore, the value of m should be greater than the value of n in order for m-n to become positive.

Answer:
3
Step-by-step explanation:
Following the rules of bedmas, we have to solve the brackets first.
[(18 + 3 · 2) ÷ 8 + 5 · 3] ÷ 6
[(18 + 6) ÷ 8 + 5 · 3] ÷ 6
[(24) ÷ 8 + 5 · 3] ÷ 6
- Now divide and multiply the values in the brackets.
(3 + 15) ÷ 6
(18) ÷ 6
= 3
