Answer 1

-7x^5 - 6x^4 + 4x^3


How many sets of numbers do you see?

Answer 2

\(\large \begin{array}{cccllll}
-7x^{\color{red}{ 5}}&-6x^4&+4x^3\\
\uparrow &\uparrow &\uparrow \\
\end{array}\)

Answer 3

@solexie how many arrows do you see?

Answer 4

3 @MathLegend

Answer 5

Good so there are 3 terms... because you must realize that the signs separate the terms... so we have

-7x^5 is one term
-6x^4 is one term
4x^3 is one term

Answer 6

so is it a quartic trinomial @MathLegend

Answer 7

Degree is simply the highest exponent... so what is the degree?

Answer 8

5

Answer 9

Oh so it must be a quintic trinomial @MathLegend

Answer 10

Yes!

Answer 11
