Question

Organize the following polynomial expressions from least to greatest based on their degree:
x + 2xyz
9x3y2
18x2 + 5ab - 6y
4x4 + 3x2 - x - 4

A.III, I, IV, II
B.IV, I, II, III
C.III, II, IV, I
D.IV, III, I, II

Answer 1

hint: the degree of a polynomial is the greatest power of the variables.

Answer 2

so for the 1st polynomial: the degree is 1,
the second is 3
and so on.

Answer 3

Does this help you a bit?

Answer 4

yes

Answer 5

You'd notice that in the second polynomial, x is to the power of 3, and y is to the power of 2. Since numerically 3 is larger than 2, the degree of that poly is 3.
