Answer:
The answer is -4.
Step-by-step explanation:
To find the answer to this problem, we must first substitute 3 into the expression --
3² - 5(3) + 2
Then, we evaluate the expression using PEMDAS --
Parentheses : 3² - 15 + 2
Exponents : 9 - 15 + 2
There is no Multiplication or Division in this problem, so we skip those steps.
Addition and Subtraction : -4
