What is the correct order of operations for simplifying the expression 2 – 3x + 5 + 7(y – 5x)2 + x?

Answer:
square the binomial , distribute 7 inside the parenthesis, and then combine like terms
Step-by-step explanation:
2 – 3x + 5 + 7(y – 5x)^2 + x
We use order of operations, PEMDAS
We start with parenthesis
So we do (y-5x)^2 ----> square the binomial
2 – 3x + 5 + 7(y^2-10x+25) + x
Then as per the order of operation, we distribute 7 inside the parenthesis
after removing the parenthesis we combine like terms
so order of operation is
square the binomial , distribute 7 inside the parenthesis, and then combine like terms
Answer: D. square the binomial, distribute 7 inside the parentheses, and then combine like terms
I just took the test on edge, this is correct :)
