Question

Which polynomial represents the difference below?2x^2 + 7x+6(3x^2 - x)O A. 2x^2 + 5x + 6B. 2x^2 + 4x + 6c. - x^2 + 6x + 6D. - x^2 + 8x+ 6

Answer 1

The given polynomials are as ,

`\begin{gathered} 2x^2+7x+6\text{ and} \\ 3x^2-x \end{gathered}`

We have to subtracrt these given polynomials,

`\begin{gathered} =2x^2+7x+6-3x^2-(-x) \\ =2x^2+7x+6-3x^2+x \\ =-3x^2+2x^2+7x+x+6 \\ =-x^2+8x+6 \end{gathered}`

Option D is correct.
