can someone please help me with these question for a medal and fan?
What are the parts that make up a polynomial expression and how are they used to classify polynomials? How are the properties of exponents used when multiplying or dividing two monomials? How is the distributive property used when finding the product of two polynomials?
polynomial can be either classified by number of terms or by degree
if by number of terms: This is a monomial \[3x^2\]and this is a binomial \[x^2 +2x\]
3 terms = trinomial like \[x^2 +4x + 6\]
anything above are just call polynomial
ok so I understand how they are classified now thank you can you help with the other questions please
if we are classifying it by degree
\[2x^5\] is a 5th degree polymial and \[10x^2\] is a 2nd degree polynomial
when you divide same numbers with different powers you can just minus off the power, i.e: \[\frac{ 2^{10} }{ 2^4 } = 2^{10-4} = 2^6\]
its the same thing for multiply except you add the power
\[3^5 \times 3^7 = 3^{5+7} = 3^{12}\]
wait are you answering the second question
yea
I don't get it
which part?
I just don't understand the way that applies to the second question. could you try to re-explain it to me?
It says properties of exponents used in multiplying or dividing monomial
you understand whats an exponent?
yes
and monomial?
kinda could you explain that to me please
its a polynomial with a single term like\[3x\]\[2x^4\]
ok I get it
you have learn multiplying/dividing indices yet?
nope
ok it looks something like this
\[\frac{ 2^5 }{ 2^3 } = \frac{ 2 \times 2 \times 2 \times 2 \times 2 }{ 2 \times 2 \times 2 } \]
then you realize you can cancel 3 of the 2s out in the fraction so it becomes 2 x 2 which is 2^2
thats for dividing
ok I get it but it still doesn't give an answer to the second question
so in short you can just take the numerator power minus the denominator's one
its asking you to use that property of exponent in monomial
no its not it asking How are the properties of exponents used when multiplying or dividing two monomials?
its behaves the same way
as with normal integers
ok can I have help with the last question please
you know whats distributive property?
distributive property is like \[y(5x+y) = 5xy + y^2\]
as for the how part, we can multiply the terms from 1st polynomial with the 2nd
\[(a+b)(x+y) = ax + ay + bx + by\]
this pretty much explains it all
you can understand that?
no
ill do it with numbers \[2(3 + 4) = 2(3) + 2(4)\]
this is distributive property
I understand that that's distributive property but I still don't understand how to answer the question how does this go together with finding the product of two polynomials
When multiplying two polynomials together, we use the distributive property to multiply every term of one polynomial is multiplied times every term of the other polynomial then simplify your answer by combining any like terms.
sounds good?
yes thank you I was having the same problem trying to understand how what you said went together with the second question
ikr i have no problem doing questions but explaining is hella hard
could you just tell me the second question then so I can get this over with please
im finding sites to copy paste from lel
Exponents represent repeated multiplication, \[a \times a =a^2\]\[a^2 \times a^3 = (aa)(aaa) = a^{2+3} = a^5\]
you understand everything so far?
yes
i don't find any good paragraphs to copy paste so far, so you might need to demonstrate the properties
I don't think I will be aloud to do that you don't know the answer?
i don't know how to describe it
When monomials include both a number and a variable, the number is called the coefficient. For example, in the monomial 8x2, 8 is the coefficient. The variables in a monomial can have whole number exponents, but no negative exponents. Just as numbers can be multiplied and divided, monomials with variables can also be multiplied and divided following the same rules.
this might be the best i found so far
thanks
