Answer:
Step-by-step explanation:
first lets put this in standard form to make it easier
- - 4x + 10
this form is the standard form (exponents go from greatest to least)
The degree in this polynomial is the highest exponent
So the degree is 3
There are 4 terms in this equation
7x^3
-5x^2
-4x
and 10
hope this helps <3
