What is the leading term, leading coefficient, and degree of this polynomial f(x)=−2x3(x+5)4(x−3)2?

Explanation:
You first express the the polynomial in its canonical form consisting of a conbination of monomials, you get:
${\displaystyle -2x^9-8x^8-198x^7+620x^6+2050x^5-1500x^4-11250x^3}$
The degree is the term with the greatest exponent, which is in this case 9.
The leading term is ${\displaystyle -2x^9}$, and the leading coefficient is -2, and the degree of this polynomial is 9.
