Answer:
Leading coefficient: -22
Degree: 2
Explanation:
The given polynomial is:
-10v-18+v²-23v²
solving like terms, we get
-22v² - 10v - 18
The leading coefficient is the coefficient of the term with the highest degree. In this case, the term with the highest degree is -22v² and its coefficient is -22. Therefore, the leading coefficient is -22.
The degree of a polynomial is the highest power of the variable in the polynomial. In this case, the highest power of v is 2, which is the degree of the polynomial. Therefore, the degree of the polynomial is 2.
