Question

Which polynomial represents the difference below?2x^2 +7x+6(3x^2 - x)O A. -x2 + 8x+ 6O B. 2x2 + 4x + 6O c. 2x2 + 5x 4°6O D. -x2 + 6x+ 6

Answer 1

Step 1

Write the difference

`(2x^2+7x+6)\text{ - \lparen3x}^2-x\text{\rparen}`

Step 2

`\begin{gathered} 2x^2+7x+6-3x^2+x \\ Add\text{ similar terms} \\ \\ -x^2+\text{ 8x + 6} \end{gathered}`

Final answer

`A.\text{ -x}^2+8x+6`
