What is the linear coefficient in (4x^2+0x-9)?

Answer and explanation

Correct answer: (0)

The direct answer is D: 0. A quadratic expression has the form \(ax^2+bx+c\). The linear term is the term containing exactly one power of x, namely \(bx\). In \(4x^2+0x-9\), the linear term is explicitly \(0x\), so its coefficient is 0. Option D is therefore correct. Option A, 4, is the coefficient of the quadratic term \(x^2\), not the linear term. Option B, -9, is the constant term, which contains no x. Option C, 9, is not even the constant coefficient because the expression contains -9. The zero is written to make the missing linear term visible; even if \(0x\) were omitted, its coefficient would still be zero. Memory cue: match the coefficient with the power: x² uses a, x uses b, and the number alone is c.
