81=2x^2/(0.5-x)(0.5-x)

Solution for 81=2x^2/(0.5-x)(0.5-x) equation:

81=2x^2/(0.5-x)(0.5-x)

We move all terms to the left:

81-(2x^2/(0.5-x)(0.5-x))=0


Domain of the equation: (0.5-x)(0.5-x))!=0

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

-x)(0.5-x)!=-0.5

x∈R


We add all the numbers together, and all the variables

-(2x^2/(-1x+0.5)(-1x+0.5))+81=0

We multiply parentheses ..

-(2x^2/(+x^2-0.5x-0.5x+0.25))+81=0

We multiply all the terms by the denominator


-(2x^2+81*(+x^2-0.5x-0.5x+0.25))=0


We calculate terms in parentheses: -(2x^2+81*(+x^2-0.5x-0.5x+0.25)), so:

2x^2+81*(+x^2-0.5x-0.5x+0.25)

We multiply parentheses

2x^2+81x^2+0x+0x+20.25

We add all the numbers together, and all the variables

83x^2+2x+20.25

Back to the equation:

-(83x^2+2x+20.25)


We get rid of parentheses

-83x^2-2x-20.25=0

a = -83; b = -2; c = -20.25;
Δ = b2-4ac
Δ = -22-4·(-83)·(-20.25)
Δ = -6719
Delta is less than zero, so there is no solution for the equation
