Question

I need help!? please? :)



How do you do these kind of problems?

Classify the expression 7x3 + 2x2 – 9x as a monomial, binomial, trinomial or polynomial.

Answer 1

what is the highest power

Answer 2

HI MAGEN!!!

Answer 3

i'm not very good at math talk....highest power?

Answer 4

hi Darris

Answer 5

Monomial = x2

Binomial = 3x2 + 2x

Trinomial = 5x4 + 3x2 + 8

Zero polynomial = When all the coefficient of polynomial is zero.
learn from it.

Answer 6

So ur given expression is a trinomial...@magenxoxo

Answer 7

what is the highest exponent that the x values have that is thier power-degree

Answer 8

uhm 9? @jonask

Answer 9

okayy...what does, monomial, binomial, trinomial or polynomial. mean? (stand for)?

Answer 10

the question you asked is\[7x^3+2x^2-9x\]
the numbers before the x dont matter
wat matters is the once raised to the top can you notice any

Answer 11

9 is not the raised number

Answer 12

ooh! I didn't realize they were there. so then its 3?

Answer 13

yes so actually we have 3,2,1 but the highest is 3

Answer 14

if the equation had only 1 as the highest it will be called monomial 'mono means 1'
if the equation had only 2 as the highest power then binomial 'bi means 2'
if the equation had only 3 as the highest power then trinomial ' tri means 3'

Answer 15

oh! I get it now!!! :D So, since it's 3 then the answer would be trinomial. correct?

Answer 16

yes

Answer 17

Thank you!

Answer 18

whats poly?

Answer 19

0?

Answer 20

poly means many i think so

Answer 21

yes a polynommial is generally n power as the highest\[P(x)=a_nx^n+a_{n-1}x^{n-1}+...+a_1x+a_0\]
obviusly the highest degree is n here
