Which option has degree (3) and a negative leading coefficient?

Answer and explanation

Correct answer: \(-6x^3+x^2-5\)

The degree of a polynomial is the greatest exponent of the variable, and the coefficient of that term is called the leading coefficient. In \(-6x^3+x^2-5\), the greatest exponent is 3 and the coefficient of \(x^3\) is \(-6\), which is negative. Therefore, option B is correct. Option A also has degree 3, but its leading coefficient, \(4\), is positive. Exam tip: identify the highest-power term first, then check the sign of its coefficient.
