The choices b and c are equivalent to 
.
Step-by-step explanation:
Step 1:
First, we need to bring the fraction to its simplest form. To do so, we divide the numerator and the denominator by the greatest factor.
The greatest factor for 4 and 6 is 2. So we divide it by 2.
So 
.
Step 2:
Similarly, we need to do the same for all the given four options.
a. 
, the greatest factor for 2 and 4 is 2. So we divide the fraction by 2.
So 
.
b. 
, the greatest common factor for 8 and 12 is 4. So we divide the fraction by 4.
So 
.
For options c and d, 1 is the greatest factor so they cannot be simplified. They remain as they are.
Step 3:
So options b and c are equal to the simplification of i.e. 
.
4w+x-4
Because when multiplying by a negative with a negative you will get a positive and multiplying a negative with a positive will get you a negative
