The sample size is 124.
93 of them are opposed to new shopping center.
So,
n = 124
p =
The point estimate of the population proportion = p = 0.75
q = 1 - p = 0.25
Margin of error (E) can be calculated by:
Using the values, we get:
Therefore, the margin of error is approximately 0.06 or 6%.

Firstly, we will split terms
We can group first two and last two terms
we can see that 2x^2 is common in first two terms
and 3 is common in last two terms
so, we can factor factor out 2x^2 from first group and 3 from second group
we get
we can see that each terms are multiple of 6x-1
so, we can factor out 6x-1
so, we get
