Wanna MEDAL!?! You gotta help me then! ----->

OpenStudy (agl202):

Given the expression −10p2q + 7p3q − 5q, do the following as instructed below: A: Write the polynomial in descending order. B: Classify the polynomial by the number of terms. C: State the degree of the polynomial.

Nnesha (nnesha):

when we have more than two variables we should add their exponents to get highest degree descending = start with highest degree to lowest `B` mono mial = single term ( mono means one term) binomial = bi means 2 term trinomial = tri means 3 terms polynomail = if there are more than 3 terms

Nnesha (nnesha):

lets take first term \[\huge\rm −10p^2q^1 \] q is same as q^1 so add the exponents of p and q 2+1 =2 degree of -10p^2q^1 is 3 now find degree of other terms

OpenStudy (agl202):

\[7p ^{2}q = 3\] Right?

Nnesha (nnesha):

it's p to the 3rd power

OpenStudy (agl202):

So, \[7p ^{3}q\]

Nnesha (nnesha):

\[\huge\rm −10p^2q + 7p^3q − 5q \] this is ur question

Nnesha (nnesha):

yes it's 7p^3q

OpenStudy (agl202):

K, next what do I do?

Nnesha (nnesha):

so what would be degree of 7p^3q

OpenStudy (agl202):

Hmmm.... I'm not sure

Nnesha (nnesha):

just add the exponent of both variable .. just like i did for first one

Nnesha (nnesha):

remember q is same as q^1 \[\huge\rm 7p^3q^1\]

OpenStudy (agl202):

Ya, I know ^. -12p^5q^3 right?

Nnesha (nnesha):

hmm how did you get -12 ??

Nnesha (nnesha):

\(\color{blue}{\text{Originally Posted by}}\) @Nnesha lets take first term \[\huge\rm −10p^2q^1 \] q is same as q^1 so add the exponents of p and q 2+1 =2 degree of -10p^2q^1 is 3 now find degree of other terms \(\color{blue}{\text{End of Quote}}\) look at this i just added exponent of p and q which is 2 and 1 2+1 = 3 so degree of -10p^2q is 3

OpenStudy (agl202):

k

Nnesha (nnesha):

so what's the degree of 7p^3q term ?

OpenStudy (agl202):

4

Nnesha (nnesha):

right so degree of -10p^2q is 3 degree of 7p^3q is and the degree of -5q is just one how would you write it in descending order ?

OpenStudy (agl202):

-10p*p=p^2q

Nnesha (nnesha):

\[\huge\rm −10p^2q + 7p^3q − 5q \] this is ur question for part A how would you rewrite the equation in descending order descending means start with the highest degree to lowest x^3,x^2,x is in descending order

OpenStudy (agl202):

K, Thx 4 the help! :)

Nnesha (nnesha):

hmm got it ?

OpenStudy (agl202):

ya

Nnesha (nnesha):

right so degree of -10p^2q is 3 degree of 7p^3q is and the degree of -5q is just one 7p^3q is with the highest degree so it comes first when u write it in descending order

OpenStudy (agl202):

thx

Nnesha (nnesha):

alright then..
