degree = $6$
Work Step by Step
The degree of a polynomial is equal to the degree of the leading term. The terms of the given polynomial have the following degrees: $x^2$ - degree is 2 $-10$ - degree is 0 $5x$ - degree is 1 $-8x^6$ - degree is 6 The leading term is $-8x^6$. The degree of this term is $6$. Thus, the degree of the given polynomial is $6$.
