Question

daughter got this question wrong
which could be the missing first term of the expression that when fully simplified, would be a binomial with a degree of 4? select 3

------ -5xy3+9x2y

1. 0
2. 5xy3
3. 9x2y
4. 8y4
5. 4xy3

she chose 2,3,5 and was wrong....

does the 1.zero just not be considered so it would be 1,3,5 the answer?

Answer 1

@depression i think this is right i dont know just help me and back me up

Answer 2

IF its not 2,3,5 then that makes it what

Answer 3

answer 2 would cancel out i think

Answer 4

and then it wouldnt be a binomial

Answer 5

When fully simplified, you have a binomial with a degree of 4

That means you have two terms

Yes, exactly! That's why B isn't a possible answer

Answer 7

Answer 8

And to answer the original question in your post
re: does the 1.zero just not be considered so it would be 1,3,5 the answer?

That's correct!

Answer 9

ooh last question difference between power and degree? are those interchangeable terms

Answer 10

Yeah they're similar and sometimes used interchangeably but to be more accurate

Degree tells us the order of the polynomial. And so you can have multiple variables and terms like x^2y^3 + 2xy. The degree tells us the highest exponent. So the first term has exponents of 2 and 3 so it has a degree of 5.
Power is another word for the exponent. ex. 2 to the power of 3 is 8.

Answer 11

omg thanks! i needed that clarified so badly lol

Answer 12

Of course!
