614. If a = 3, b = -2 and c = 4 then what is the value of a2-2b+c? [Circle Postal Rajasthan Examination-2007]

Correct Answer: Correct answer is: (C) 17.

Exam Relevance: SSC, Bank PO, CAT, MAT

Concept notes: The problem involves substituting given values into an algebraic expression and performing arithmetic operations.

Common Mistakes: Students may make errors in arithmetic operations or misinterpret the order of operations.

Calculate \(-2b\): \[ -2b = -2(-2) = 4 \] 3. Add the value of \(c\): \[ c = 4 \] 4. Combine all parts: \[ a^2 - 2b + c = 9 + 4 + 4 = 17 \] Thus, the value of the expression is 17.

Option Analysis:

Option A: 15 is incorrect because it does not account for the correct arithmetic operations.
Option B: 16 is incorrect because it does not account for the correct arithmetic operations.
