Evaluating for
To evaluate the polynomial expression when , substitute for every instance of the variable and simplify using the order of operations. First, perform the substitution: . Next, evaluate the exponent: , which updates the expression to . Then, perform the multiplications from left to right: and (since subtracting a negative product is equivalent to adding), giving . Finally, add the terms to find the result, which is .
