Which option simplifies to the linear polynomial (2x+5)?
Answer and explanation
Correct answer: \(5x-3x+5\)
In \(5x-3x+5\), \(5x\) and \(-3x\) are like terms. Combining them gives \(2x\), so the expression becomes \(2x+5\). Option B has the constant term \(-5\), while option C contains \(x^2\), so it is not linear. Exam tip: Combine only terms with the same variable and exponent.
