The classification of the polynomials include:
a. x²+ 3x + 2x – 2x²
= x² – 2x² + 3x + 2x
= -x² + 5x
Since it has two terms, it is a binomial
b. x³+ 4x – 4x – 4x²
= x³ – 4x² + 4x – 4x
= x³ – 4x²
Since it has two terms, it is a binomial
c. x³+ 2x – x³ – 2x² + 3
= x³ – x³ – 2x² + 2x + 3
= – 2x² + 2x + 3
Since it has three terms, it is a trinomial
