Question

5. Write down the degree of the following polynomial:

(a) 18ab + 15a – abc
(b) 3a2 +6a +3
(c) 11ab2 – 10ac +4

(d) 2x2 + 3xy + x2 y
(e) x2 + y3 + x2y3​

Answer 1

Step-by-step explanation:

8. Compare

6/-11 and -4/9

Answer 2

(a) $18ab+15a-abc$ ➜ 3

The degree of the above polynomial is 3 because the total power of $abc$ is 3.

(b) $3a^{2}+6a+3$ ➜ 2

The degree of the above polynomial is 2 because the highest power of $a$ is 2.

(c) $11ab^{2}-10ac+4$ ➜ 3

The degree of the above polynomial is 3 because the total power of $ab^{2}$ is 3.

(d) $2x^{2}+3xy+x^{2}y$ ➜ 3

The degree of the above polynomial is 3 because the total power of $x^{2}y$ is 3.

(e) $x^{2}+y^{3}+x^{2}y^{3}$ ➜ 5

The degree of the above polynomial is 5 because the total power of $x^{2}y^{3}$ is 5.
