What is the simplified form of (17x-8x+5)?
Answer and explanation
Correct answer: \(9x+5\)
Combine the like terms \(17x\) and \(-8x\): \(17x-8x=9x\). The constant term \(+5\) remains unchanged, so the simplified expression is \(9x+5\). In \(9x-5\), the sign of the constant term has been changed incorrectly. Exam tip: Add or subtract only terms having the same variable and exponent.
