Question

Which polynomial is twice the sum of 4x^2 – 1 + 1 and - 6x^2+ x - 4?

Answer 1

Answer:

3

Step-by-step explanation:

The sum of these two polynomials is  - 2 x^2  - 3. the two x variables are additive inverses and  -6 x^2 and  4 x^2  equal  - 2 x^2 and  -3 results from  -4 and 1

Multiplying the sum by 2 gives us - 4 x^2 - 6 . Answer 3
