What is the simplified form of \(9x^2+5x^2\)?

Answer and explanation

Correct answer: \(14x^2\)

\(9x^2\) and \(5x^2\) are like terms because they have the same variable raised to the same power. Therefore, add their coefficients: \((9+5)x^2=14x^2\). The exponent does not change during addition, so \(14x^4\) is incorrect. Exam tip: when adding like terms, add only the coefficients and keep the variable part unchanged.
