Answer

$x=\{ -3,1 \}$

Work Step by Step

Equating each factor to zero (Zero Product Property), then \begin{array}{l}\require{cancel} x-1=0 \\\\\text{OR}\\\\ x+3=0 .\end{array} Solving each equation results to \begin{array}{l}\require{cancel} x-1=0 \\\\ x=1 \\\\\text{OR}\\\\ x+3=0 \\\\ x=-3 .\end{array} Hence, the solutions are $ x=\{ -3,1 \} .$
