Question 162242
Classify the 15 given polynomials as monomials, binomials, trinomials, and polynomials. Use the format given below for categorizing the polynomials. 
a. 4x2 + 3x + 7 
b. ax2 + 2abx + c2 
c. 6a3 - 7b2 
d. 2ab + 7cd - 5da 
e. -3abc 
f. 10x - 5x + 4x 
g. 2a2 + 3b2 - 2c2 + 2d2
h. 7x3 + 8x2 
i. 14y 
j. xyz - x + 2x 
k. x3 - y3 + z3 - 3xyz 
l. 3xy + 3x 
m. 4b3
n. 2x3 - 9y3 
o. x - 8y - 9x
------------------
Count the terms.  If there's 1, it's "mono", 2 is bi, 3 is tri.  4 or more is usually called "poly", meaning many.
A term is a group standing alone, such as -3abc in e.  If there's more than one term, it will be connected by a + or - sign.
