Question

решить неравенство по алгебре ​

Answer 1

(x+5)*(x-1)*(x-4)<0

$\left \{ {{(x+5)*(x-1)<0} \atop {x-4>0}} \right.\\\left \{ {(x+5)*(x-1)>0} \atop {x-4<0}} \right.$

$\left \{ {{x∈(-5,1} \atop {x>4}} \right.\\\left \{ {{x∈(-∞,-5)∪(1,+∞)} \atop {x>4}} \right.$

x∈∅

x∈(-∞,-5)∪(1,4)

x∈(-∞,-5)∪(1,4)
