Consider the inequality (x+3)(x1)0 and the function f(x)0.
It can be written as
f(x)=(x+3)(x1)
It is clear that the function has x-intercept at -3, 1.
In the expression x+3x10, multiply both sides by (x1)2:
x+3x10
x+3x1×(x1)20×(x1)2
(x+3)(x1)0
Since both expressions are same, both have the same solution sets.
Conclusion: The provided inequalities have the same solution sets.
