Degree of a Polynomial :

Degree of a polynomial is defined as the highest power of its variable that appears with nonzero coefficient

When a polynomial has more than one variable, we need to find the degree by adding the exponents of each variable in each term.

Solution :

Step 1 of 2 :

Write down the given polynomial

The given polynomial is 7x⁵ + 8x² - 5x + 3

Step 2 of 2 :

Find degree of the polynomial

The variable is x

Now the highest power of its variable that appears with nonzero coefficient is 5

Hence degree of the polynomial 7x⁵ + 8x² - 5x + 3 is 5

Correct question :

Degree of the polynomial 7x⁵ + 8x² - 5x + 3 is

a) 1 b) 3 c) 2 d) 5
