Given
[tex]\left(8x²+9\right)-(6x²+2x+2)[/tex]To find: The difference.
Explanation:
It is given that,
[tex]\left(8x²+9\right)-(6x²+2x+2)[/tex]That implies,
[tex]\begin{gathered} \left(8x²+9\right)-(6x²+2x+2)=(8x^2-6x^2)-2x+(9-2) \\ =2x^2-2x+7 \end{gathered}[/tex]Hence, the answer is option B. 2x² - 2x+7.
