Question

Please help?
Choose the polynomial that is written in standard form.
Choose one answer.
a. 2x3y2 + 4x4y + 8x7
b. −3x4y2 + 4x4y5 + 10x2
c. 6xy2 + 4x3y8 + 9x2
d. −2x5y3 + 4x2y2 + x2

Answer 1

a polynomials standard format is as follows
a_0x^n+a_1x^n-1+.....a_nx^0
i.e it follows decreasing powers

Answer 2

Standard form means terms are in decreasing order of degree.

The degree of a term is the sum of all the powers in that term.

Answer 3

Only one of your choices fits the criteria for standard form... which one?

Answer 4

is it d @debbieG

Answer 5

I Think It is D

Answer 6

msg me ; )

Answer 7

\( \Large −2x^5y^3 + 4x^2y^2 + x^2\)

The terms have degrees: 8, 4, 2, so yes, it's d. :) You can also confirm that none of the others have terms in decreasing order of degree.

Answer 8

I appreciate the help! @debbieG
