Which expression is obtained by adding (x^2+x-4) to (2x^2-3x+1)?

Answer and explanation

Correct answer: \(3x^2-2x-3\)

To add the polynomials, combine like terms: \(2x^2+x^2=3x^2\), \(-3x+x=-2x\), and \(1-4=-3\). Therefore, the resulting expression is \(3x^2-2x-3\). Option B has an error in adding the \(x\)-terms. Exam tip: add the \(x^2\)-terms, \(x\)-terms, and constants separately.
