The expression is not equivalent to \rm 28x-16.

<h2>Polynomial</h2>

An expression of more than two algebraic terms, basically sums of terms and variables of power n.

<h2>Given</h2>

2x+2 ,\ 2x,\ 3x-8, 4,\ 7x-2,\ -2,\ 5x,\ 2x-4,\ 8x,\ -x-6

<h2>Step by step explanation</h2>

\rm Equivalent\ expression = add\ all\ the\ given\ terms.\\&#10;Equivalent\ expression = 2x+2+2x+3x-8+4+7x-2-2+5x+2x-4+8x-x-6\\&#10;Equivalent\ expression = 2x+2x+3x+7x+5x+2x+8x-x+2-8+4-2-2-4-6\\&#10;Equivalent\ expression = 28x-16\\&#10;

Then the expression is not equivalent to \rm 28x-16.

Thus, the expression is not equivalent to \rm 28x-16.
