Final answer:
To evaluate the expression n² - 5n + 2, a specific value of 'n' must be substituted into the equation. Without a specific value, the quadratic formula can be used to find the potential values of 'n'. The formula yields two solutions based on the plus or minus sign used.
Step-by-step explanation:
The question seems to involve evaluating a quadratic expression given a certain value of 'n', although the specific value to use for 'n' is not provided in the question. The expression given is n² - 5n + 2. To evaluate this expression, one would simply substitute the given value of 'n' into the expression and perform the arithmetic operations.
Without a specific value for 'n', a general solution involves factoring the quadratic, if possible, or using the quadratic formula where a is the coefficient of n², b is the coefficient of n, and c is the constant term.
The quadratic formula is given by x = -b ± √(b² - 4ac) / (2a). This would give two possible solutions for 'n' depending on whether you use the + or - sign.
