Question

If a=2, b=3, c=-1, then what is the answer to the problem a^2 - 2b + (3 + c)^2?

a) 1
b) 6
c) 11
d) 10

Answer 1

Upon calculating the individual parts of the expression, the correct answer turns out to be 2, which is not listed in the provided choices, suggesting an error in the question or answer choices.

Step-by-step explanation:

The question asks for the value of the expression a^2 - 2b + (3 + c)^2 when a=2, b=3, c=-1. First, calculate a^2 which is 2^2 or 4. Next, calculate 2b which is 2*3 or 6. Then, calculate (3 + c)^2 which is (3+(-1))^2 or (2)^2 or 4.

Combine these values according to the expression: 4 - 6 + 4, which simplifies to 2. Thus, the correct answer is 2, but this option is not listed in the provided choices, indicating a possible error in the question or answer choices.
