Answer:
the degree is 2
Explanation:
because when you distribute x - 2 to x+3 = x^2 - x - 6. When you see an exponent in a trinomial that's the degree. If it's polynomial and has multiple exponents the degree is the highest number of the exponents.
Example:
2x^5 + x^3 - 4x + 1
The degree of this polynomial is 5 since it's the highest exponent number.
