Answer:

Step-by-step explanation:

4(2)² + 4(2) - 2

Use PEMDAS, which is Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction. In that order we evaluate.

Exponents first, since there is nothing else to do in the parenthesis.

4(2)² + 4(2) - 2

4(4) + 4(2) - 2

Next is Multiplication and Division

4(4) + 4(2) - 2

16 + 8 - 2

Lastly are Addition and Subtraction

16 + 8 - 2

16 + 6
