\: \Large \mathbb{SOLUTION:}


\: \: \rm{ {7x}^(2) + 4x - {x}^(2)}


\: \: \text{Reorder and gather like terms}


\: \: \rm{( {7x}^(2) - {x}^(2) ) + 4x}


\: \: \text{Collect coeffiecients of like terms}


\: \: \rm{(7 - 1) {x}^(2) + 4x}


\: \: \text{Calculate the sum or difference}


\: \: \rm{ \underline{ \underline{ {6x}^(2) + 4x}}}
