Answer:

Step-by-step explanation:

The very first step is to take (6 - 8) = - 2    Do the brackets first.

Now square the result (-2)^2 = 4                Multiply by 4

4*4 = 16 These fours are different. The first is the brackets, The second is what is out side the brackets.

Last step: 16 + 3                                          The answer is 19.

19 is not what you asked for, but it's a good idea to see how to continue.
