Question

Which polynomial represents the difference below? 2x^7 - 6x+ 3 - (9x^8 + 4x)

Answer 1

Given data:

The given expression is 2x^7 - 6x+ 3 - (9x^8 + 4x)​.

The given expression can be written as,

$\begin{gathered} 2x^7-6x+3-(9x^8+4x)=2x^7-6x+3-9x^8-4x \\ =-9x^8+2x^7-10x+3 \end{gathered}$

Thus, the option (B) is correct.
