Odpowiedź :
a)
5(x-4)(x+3) > 0 |:5
(x-4)(x+3) > 0
x-4=0 ∨ x+3=0
x=4 ∨ x=-3
x∈(-∞,-3)∪(4,∞)0
b)
-8(x+10)(x-1) < 0 |:(-8)
(x+10)(x-10) > 0
x+10=0 ∨ x-10=0
x=-10 ∨ x=10
x∈(-∞,-10)∪(10,∞)
c)
(x+6)(x-6) > 0
x∈(-∞,-6)∪(6,∞)
d)
x(x+12) ≥ 0
x=0 ∨ x+12=0
x=0 ∨ x=-12
x∈(-∞,-12>∪<0,∞)
e)
3(x+2)(x-1) ≤ 0 |:3
(x+2)(x-1) ≤ 0
x+2=0 ∨ x-1=0
x=-2 ∨ x=1
x∈<-2,1>
