Answer:

Step-by-step explanation:
Given the rational expression:
, to express this in simplified form, we would need to apply the concept of partial fraction.
Step 1: factorise the denominator





Thus, we now have: 
Step 2: Apply the concept of Partial Fraction
Let,
= 
Multiply both sides by (x - 1)(x - 4)
= 

Step 3:
Substituting x = 4 in 





Substituting x = 1 in 





Step 4: Plug in the values of A and B into the original equation in step 2


I think the answer would be D. Hope this helps!
The first one is A and then the next one I believe should be 210 for both
TSR because if u look at the lines of where their similar on the second one you match it up
You’ll get your answer by adding +7 to each number.
