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
