Answers:
degree = 6
leading coefficient = -20
Step-by-step explanation:
The degree is the largest exponent. This applies for single variable polynomials only. In this case the degree is 6.
The largest exponent term is -20u^6 showing us that the leading coefficient is -20. If we sorted the terms from largest exponent to smallest exponent, then we get the standard form: -20u^6+5u^5+15u^3+3u
Once a polynomial is in standard form, the degree and leading coefficient are much easier to spot.
