(2x7 + 7x4 + 6) - (2x4 - x)= _____A.2x7 + 9x4 - x + 6B.6x3 + 6C.2x7 + 5x4 + x + 6D.4x11 + 6x3 +6

To subtract one polynomial from another, you subtract like terms. Like terms are terms that have the same variable and exponent.

The given polynomials are (2x^7 + 7x^4 + 6) and (2x^4 - x).

Subtract the second polynomial from the first:

2x^7 + 7x^4 + 6 - (2x^4 - x)

Distribute the negative sign to each term in the second polynomial:

2x^7 + 7x^4 + 6 - 2x^4 + x

Combine like terms:

2x^7 + (7x^4 - 2x^4) + 6 + x

This simplifies to:

2x^7 + 5x^4 + x + 6

So, the answer is C. 2x^7 + 5x^4 + x + 6.
