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
