Question 2
Determine the degree of each of the following polynomials.
(i) $2x-1$

(ii) $-10$

(iii) $x^3-9x+3x^5$

(iv) $y^3(1–y^4)$

Answer 1

(i) The degree of the polynomial $2x–1$ is one because the highest exponent of x is one.

(ii) The degree of the polynomial $-10or-10x^0$ is zero because the exponent of x is zero.

(iii) The degree of the polynomial $x^3-9x+3x^5$ is five because the highest exponent of x is five.

(iv) Degree of polynomial $y^3(1-y^4)$ or $y^3–y^7$ is seven because the highest exponent of y is 7.
