Enter the values for the highlighted variables that show how to subtract the rational expressions correctly

A = 6
x^2 + 6x is equal to x(x+6)
b=2
Denominator and numerator of the first term are multiplied by x. 
c=6
Second term is multiplied by (x-6)/(x-6)
d=2
Now that they have the same denominator, the two terms are combined. 2 is the coefficient of the first term
e=6
In the same way as d is carried over from b, e is carried over from c. 
f = 6
2x - x + 6 = x + 6
g = 1 
We factor out the (x+6) from the numerator and denominator

The values of the highlighted variables can be obtained by comparing the

results of the steps of the subtraction process.

The values are;

a = 6b = 2c = 6d = 2e = 6f = 6g = 1

Reasons:

The given rational expression is presented as follows;

By comparing the above equation, to the question, we have;

x·(x + 6) = x·(x + a)

Therefore;

a = 6

By comparing the above expression, we have;

2·x = b·x

∴ b = 2

(x - 6) = (x - c)

∴ c = 6

By comparing, we have;

2·x - x + 6 = d·x - x + e

∴ d = 2, e = 6

Comparing gives;

x + 6 = x + f

f = 6

Therefore; g = 1
