What is the simplified form of (3x^2+0x-7)?

Answer and explanation

Correct answer: \(3x^2-7\)

For every value of \(x\), \(0x=0\). Hence, \(3x^2+0x-7=3x^2-7\), so option A is correct. Option B incorrectly adds an \(x\)-term, although its coefficient is 0. Exam tip: Remove any term whose coefficient is 0 when simplifying a polynomial.
