Equation : a^2 + ( 2b - c) x d, solve for a=2, b=5, c=8, and d= pls and work

The first step for solving this expression is to insert the numbers for a, b, c, and d. This will change the expression to the following:
2² + (2(5) - 8) x 4
Now we need to evaluate the power of the first number.
4 + (2(5) - 8) x 4
Next you'll multiply the first two numbers in the parenthesis together.
4 + (10 - 8) x 4
Subtract the numbers in the parenthesis
4 + 2 x 4
Now multiply the two numbers together (remember PEMDAS)
4 + 8
Finally,, add the two numbers together to get your final answer.
12
This means that the correct answer to your question is going to be 12.
