Answer

$(-\infty,-4) \cup (1, \infty)$

Work Step by Step

$(x+4)(x-1)\gt0$ $(x+4)(x-1) =0$ Solve as an equation. $x=-4$ $x=1$ Plot these numbers on a number line,split them into intervals, take one test point from each interval, and check them to see if they are true. If they are true, then it is a solution. In this case, it is $(-\infty,-4) \cup (1, \infty)$
