Answer

$0$

Work Step by Step

Since the grouping symbol is preceded by a negative sign, then the sign of each term inside the grouping symbol alters once the grouping symbol is removed. Hence, the given expression, $ 5x^4+3x-(5x^4+3x) $, is equivalent to \begin{array}{l}\require{cancel} 5x^4+3x-5x^4-3x .\end{array} By combining like terms, then this simplifies to \begin{array}{l}\require{cancel} (5x^4-5x^4)+(3x-3x) \\\\= 0 .\end{array}
