Combine like terms
7x2 + x + 3
Analyze the 3 terms of the polynomial 7x2 + x + 3
Analyze Term 1
Term 1 is 7x2
Our coefficient/constant is 7
Our variable piece is x
Raise our variable to the power of 2
Analyze Term 2
Term 2 is x
Since there is no coefficient
our coefficient is 1
Our variable piece is x
No exponent exists for this term
Analyze Term 3
Term 3 is 3
Our coefficient/constant is 3
This term has no variable, so it is a constant
No exponent exists for this term
Determine the Degree of the Polynomial:
Highest exponent for x = 2
