Question

help!:)
A. 4 - 7x5 + x2
B. 5x3 + 5 - 3x4
C. 3x + 2x4 - x2 + 6
D. 3x3 - 5 + 2x5 + x

Which of the above polynomials is a 4th degree trinomial?


1.Polynomial A
2.Polynomial B
3.Polynomial C
4.Polynomial D

Answer 1

4th degree implies the highest exponent is 4.
Trinomial implies three terms.

Answer 2

i think its 2

Answer 3

Look at the exponents. The highest exponent must be 4.

Answer 4

because you need 3 so that it become a trianomial and the highest power is 4

Answer 5

@vita955 which one do you think is correct?

Answer 6

It should be B, it is 4th degree since 4 is the highest power
and it is a trinomial since it has three terms
