r=1/2(r1+r2)

Solution for r=1/2(r1+r2) equation:

r=1/2(r1+r2)

We move all terms to the left:

r-(1/2(r1+r2))=0


Domain of the equation: 2(r1+r2))!=0

r∈R


We add all the numbers together, and all the variables

-(1/2(+r+r^2))+r=0

We multiply all the terms by the denominator


-(1+r*2(+r+r^2))=0


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

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

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

Wy multiply elements

2r^2(++1

We use the square of the difference formula

2r^2(+1

Back to the equation:

-(2r^2(+1)


We add all the numbers together, and all the variables

-(2r^21=0

We do not support erpression: r^21
