Which polynomial correctly combines the like terms and puts the given polynomial in standard form? x + 8x4 – x2 – x a. 8x4 – x2 – x b. 8x4 + x2 + x c. 8x4 – x2 – x d. 8x4 – x2 – x

  none of the above

  should be: 8x^4 -x^2

Step-by-step explanation:

In the problem statement given here, when like terms are combined, the x terms cancel. None of the answer choices shows that.

  x + 8x^4 – x^2 – x

  = 8x^4 -x^2 +(x -x)

  = 8x^4 -x^2

Comment on the question

Based on the answer choices, it looks like there are typos, possibly in the given polynomial, and probably the answer choices as well. Choices A, C, and D are identical as shown here.
