Open in App

Solution

We know that the degree is the value of the greatest exponent of expression (except the constant ) in the polynomial. To find the degree all that you have to do is, find the largest exponent in the polynomial.
In polynomial $7 x^{3} + 5 x^{2} + 2 x - 6$ , the value of the largest exponent is $3$ , since the first term is cube.
Then degree of the polynomial is $3$ .
