Find the Degree, Leading Term, and Leading Coefficient f(x)=10x^2+2x-9x^3

$f (x) = 10 x^{2} + 2 x - 9 x^{3}$

Simplify the polynomial, then reorder it left to right starting with the highest degree term.

Move $2 x$ .

$f (x) = 10 x^{2} - 9 x^{3} + 2 x$

Reorder $10 x^{2}$ and $- 9 x^{3}$ .

$f (x) = - 9 x^{3} + 10 x^{2} + 2 x$

The degree of a polynomial is the highest degree of its terms.

Identify the exponents on the variables in each term, and add them together to find the degree of each term.

$- 9 x^{3} \to 3$

$10 x^{2} \to 2$

$2 x \to 1$

The largest exponent is the degree of the polynomial.

$3$

The leading term in a polynomial is the term with the highest degree.

$- 9 x^{3}$

The leading coefficient of a polynomial is the coefficient of the leading term.

The leading term in a polynomial is the term with the highest degree.
