to re-arrange in standard form simply re-write the function so the exponents are in decreasing order (be careful to preserve the signs of the terms though)

Vocaloid:

addition is commutative you can re-arrange the terms so that the exponents are decreasing, b/c right now it's going from 1 to 2 to 0 which is out of order

Vocaloid:

you can switch the x and the x^2 and then the function will be in standard form

zarkam21:

okay so for a it would be standard form: m(x)=x^2+x-1

Vocaloid:

good to describe the "polynomial name' first identify the degree (highest exponent) and the number of terms

zarkam21:

x^2

zarkam21:

2x

Vocaloid:

good, so the highest exponent is 2 how many terms are there?

zarkam21:

2

zarkam21:

3

Vocaloid:

good, 3 so the name is "quadratic trinomial"

zarkam21:

degree woukd be 2?

Vocaloid:

good, degree is 2 for "leading coefficient" which term has the highest exponent?

zarkam21:

1?

zarkam21:

because it is x^2 isn't there an understood 1>

Vocaloid:

yeah, the leading coefficient is 1 ^_^ sorrythoughtyouweretalkingabouttheterm1

Vocaloid:

with that being said the constant term is 1 since that's the term with no variables in it and we're done

Vocaloid:

well, done with #6 anyway

Vocaloid:

anyway, #7 is already in standard form so just copy it down again for that problem

Vocaloid:

for "polynomial name" how many terms are there and what's the degree?

Vocaloid:

sorry if I'm kind of slow, I'm on mod duty and we have a lot of trouble makers today

zarkam21:

no its okay

zarkam21:

umm there are 2 terms?

Vocaloid:

good, and what's the highest exponent?

zarkam21:

um 1?

zarkam21:

would thi sbe monomial?

Vocaloid:

monomial means one term only since the degree is 1 we use "linear" two terms = binomial so linear binomial = answer

Vocaloid:

|dw:1515688150684:dw|

Vocaloid:

the degree is 1 leading coefficient is also 1 (since the coefficient of x is 1)

Vocaloid:

constant term is pi

Vocaloid:

start by re-writing the polynomial by re-arranging the terms in descending order of exponents

zarkam21:

standard form is 11x^3-6x^2+2

Vocaloid:

good degree and number of terms?

zarkam21:

3 and 3

zarkam21:

trinomial

Vocaloid:

|dw:1515690201790:dw| good and what about the degree? what word would we use to describe a degree of 3?

zarkam21:

cubic trinomial

Vocaloid:

good degree is 3 what is the coefficient of the highest-exponent term?

zarkam21:

11

Vocaloid:

good so leading coefficient is 11 constant term is 2
