The leading coefficient of a polynomial is the coefficient of the leading term. In this case, the leading coefficient is . A polynomial consists of terms, which are also known as monomials. The leading term in a polynomial is the highest degree term. In this case, the leading term in is the first term, which is . The leading coefficient in a polynomial is the coefficient of the leading term. In this case, the leading term is and the leading coefficient is . The polynomial degree is , the leading term is , and the leading coefficient is .
