Answer 3

for Number 1, what is the largest degree?

Answer 4

Degree of the polynomial is classified by the largest power.
\(\sf Some~Examples: \)

\(\color{#000000 }{ \displaystyle 3x^4+2x^3-7x+9 }\)
The largest power/exponent in this equation is \(4\),
therefore the polynomial is "quartic" polynomial.

\(\color{#000000 }{ \displaystyle 3x^2-5x^5+2x }\)
The largest power/exponent in this equation is \(5\),
therefore the polynomial is "quantic" polynomial.

\(\color{#000000 }{ \displaystyle x+4-7x^2+11x^3 }\)
The largest power/exponent in this equation is \(3\),
therefore the polynomial is "cubic" polynomial.

Answer 5

What is the largest power/exponent in #1 ?

Answer 6

Hey guys! Sorry, I'm back.

Answer 7

exponent 5? @SolomonZelman

Answer 8

I think @SolomonZelman meant "quintic" instead of "quantic", if that's what's confusing you.

Answer 9

Okay, thank you :) @Alphabet_Sam

Answer 10

every exponent has its own name

Answer 11

On the second one, you just need to distribute the 2x^2 and then write it in order of descending exponent value. A more in-depth explanation of Standard Form for polynomials can be found here: http://www.softschools.com/math/algebra/topics/writing_polynomials_in_standard_form/

Answer 12

Okay, thank you both so much! @SolomonZelman and @Alphabet_Sam

Answer 13

What I should have done, was post the questions separately so that I can award you both. I'll repost so that both of you can receive a medal :) thank you for all your help.
