(4x - 3)(2x - 1) > 0
When you see a situation like this;
Just look at the values of x that will give an answer of zero.
Then the answer will be: x is greater than those individual values.
Lets assume 4x - 3 = 0 then;
x = 3/4
Lets assume that 2x - 1 = 0 then;
x = 1/2
But we don't want the product of (4x - 3) and (2x - 1) to be zero so;
x has be greater than 1/2 and be greater than 3/4 hence;
x > 1/2 or x > 3/4
