Polynomial Degree and Coefficients Quiz

Polynomial Degrees and Leading Coefficients

• The degree of a polynomial is the highest power of the variable (usually x) in the polynomial.
• To find the degree of a polynomial, identify the term with the highest power of the variable.
• The degree of the polynomial $3x^4 - 2x^3 + 5x^2 - 7x + 1$ is 4, because the highest power of x is 4.

Identifying Terms with Highest Degrees

• In the polynomial $-2x^6 + 4x^3 - 6x^5 + 9x - 1$, the term with the highest degree is $-2x^6$, which has a degree of 6.
• The term with the highest degree is the term with the highest power of the variable.

Leading Coefficients of Polynomials

• The leading coefficient of a polynomial is the coefficient of the term with the highest degree.
• The leading coefficient of the polynomial $-7x^3 + 4x^2 - 9x + 2$ is -7, because the term with the highest degree is $-7x^3$.
