Domain of the equation: (1+r)!=0

We move all terms containing r to the left, all other terms to the right

r!=-1

r∈R





Domain of the equation: (1+r)^2!=0

r∈R





Domain of the equation: (1+r)^3!=0

r∈R



We add all the numbers together, and all the variables

4000/(r+1)+4500/(r+1)^2-48835.6/(r+1)^3+1000=0

We calculate fractions


(4000*(r+1)^2*(r+1)^3)/((r+1)*(r+1)^2*(r+1)^3)+(4500*(r+1)*(r+1)^3)/((r+1)*(r+1)^2*(r+1)^3)+(-48835.6*(r+1)*(r+1)^2)/((r+1)*(r+1)^2*(r+1)^3)+1000=0



We calculate terms in parentheses: +(4000*(r+1)^2*(r+1)^3)/((r+1)*(r+1)^2*(r+1)^3), so:

4000*(r+1)^2*(r+1)^3)/((r+1)*(r+1)^2*(r+1)^3

We multiply all the terms by the denominator


4000*(r+1)^2*(r+1)^3)

Back to the equation:

+(4000*(r+1)^2*(r+1)^3))





We calculate terms in parentheses: +(4500*(r+1)*(r+1)^3)/((r+1)*(r+1)^2*(r+1)^3), so:

4500*(r+1)*(r+1)^3)/((r+1)*(r+1)^2*(r+1)^3

We multiply all the terms by the denominator


4500*(r+1)*(r+1)^3)

Back to the equation:

+(4500*(r+1)*(r+1)^3))





We calculate terms in parentheses: +(-48835.6*(r+1)*(r+1)^2)/((r+1)*(r+1)^2*(r+1)^3), so:

-48835.6*(r+1)*(r+1)^2)/((r+1)*(r+1)^2*(r+1)^3

We multiply all the terms by the denominator


-48835.6*(r+1)*(r+1)^2)

Back to the equation:

+(-48835.6*(r+1)*(r+1)^2))



We add all the numbers together, and all the variables

(4000*(r+1)^2*(r+1)^3))+(4500*(r+1)*(r+1)^3))+(-48835.6*(r+1)*(r=0
