danjs · Answer

every variable is to the first power?

anonymous · Answer

i dont get it

danjs · Answer

you can combine things with the same variable terms.. like

3x2y + 4xy - 5x4y   =  
6xy   +  4xy  -  20 xy    =
(6 + 4 - 20)xy   =
-10xy

anonymous · Answer

does it apply for a.. b. nd c

danjs · Answer

yes

danjs · Answer

need to simplify it first by combining the like terms

danjs · Answer

oh you know what, are those powers?  like the first term
$$3x^2*y$$
?

anonymous · Answer

NOPE . i dont know this at allllll

danjs · Answer

They probably are,  usually put a x^2  hat for powers

danjs · Answer

So the prob is... 

$$3x^2y+4xy + 1 -5x^4 y - 6y$$

danjs · Answer

Descending order -

Largest powers of  x first,
Order the terms in decreasing powers of x

danjs · Answer

Number of terms, are how many things are added or subtracted together

danjs · Answer

the degree is the highest power

anonymous · Answer

so 5x4y is the degree

anonymous · Answer

what does it mean by classify for B

danjs · Answer

sorry, the degree for terms like x^4*y  is the sum of both variables exponents, here 4 + 1 = 5,  the degree is 5

danjs · Answer

just means how many terms are in the polynomial, here 5

anonymous · Answer

what is the polynomial by the number of terms

danjs · Answer

each term is added or subtracted together

danjs · Answer

like 3x^2*y is one term

@DanJS  can you explain this to me please? i have the same question
