Which of the following statements are true ?
A) The values of x that satisfies the inequality \(x^2-(a+b)x+ab<0\) is a<x<b where b>a
B) The values of x that satisfies the inequality \(x^2-(a+b)x+ab>0\) is x>b where b>=a
C) The values of x that satisfies the inequality \(x^2-(a+b)x+ab>0\) is a<x<b where b>=a
D) The values of x that satisfies the inequality \(x^2-(a+b)x+ab<0\) is x<a and x>b where b>=a
E) The values of x that satisfies the inequality \(x^2-(a+b)x+ab>0\) is x<a<b where b<a

can someone please provide an explanation for this problem?
I am clearly stuck.
Lets calculate the values of the first option a,
x^2-(a+b)x+ab<0
x^2 – ax – bx +ab < 0
X( x-a) -b(x-a) <0
(x-a) (x-b) <0
We are given that b>a.
