Answer 1

Is there a missing term? If so, which?

Answer 2

Start with the highest power of x, x^5. Do you see an x term that is missing?

Answer 3

The missing term is an x term.
We have an x^5 term, an x^4 term...an x^2 term, a constant term, but no x term. Do you see how that works?

Answer 4

x^3?

Answer 5

Answer 6

Rearrange the terms in descending order of exponent:

\( - 4x^5 - 2x^4 - 3x^3 + x^2 + 12 \)

Do you notice a power of x that is not there?

Answer 7

Maybe it's clearer here:

\(- 4x^5 - 2x^4 - 3x^3 + x^2 ~~~~~~~~~+ 12\)

Answer 8

\(- 4x^5 - 2x^4 - 3x^3 + x^2 + 0x^1+ 12\)
