Question 274260
<font face="Garamond" size="+2">



#1 is a polynomial of degree 2


Use the caret mark, (Shift-6, "^"), to indicate exponentiation.


1. x^2 + 2x + 2 means *[tex \LARGE x^2\ +\ 2x\ +\ 2]


2. (b^2c)/(d^4) means *[tex \LARGE \frac{b^2c}{d^4}]


3. 8xz + 1/2y means *[tex \LARGE 8xz\ +\ \frac{1}{2}y]


In which case 3 is a polynomial of degree 2.  (The degree of *[tex \Large x] in the first term is 1 and the degree of *[tex \Large z] in the first term is 1, but the degree of the term is the sum of the degrees of all of the variables in the term, so 1 + 1 = 2.)


But

8xz + 1/(2y) means *[tex \LARGE 8xz\ +\ \frac{1}{2y}] and this is NOT a polynomial.
