18=((0.05-x)(0.1-x))/(x^2)

Solution for 18=((0.05-x)(0.1-x))/(x^2) equation:

18=((0.05-x)(0.1-x))/(x^2)

We move all terms to the left:

18-(((0.05-x)(0.1-x))/(x^2))=0


Domain of the equation: x^2)!=0

x!=0/1

x!=0

x∈R


We add all the numbers together, and all the variables

-(((-1x+0.05)(-1x+0.1))/x^2)+18=0

We multiply parentheses ..

-(((+x^2-0.1x-0.05x+0.005))/x^2)+18=0

We multiply all the terms by the denominator


-(((+x^2-0.1x-0.05x+0.005))+18*x^2)=0


We calculate terms in parentheses: -(((+x^2-0.1x-0.05x+0.005))+18*x^2), so:

((+x^2-0.1x-0.05x+0.005))+18*x^2

We add all the numbers together, and all the variables

18x^2+((+x^2-0.1x-0.05x+0.005))


We calculate terms in parentheses: +((+x^2-0.1x-0.05x+0.005)), so:

(+x^2-0.1x-0.05x+0.005)

We get rid of parentheses

x^2-0.1x-0.05x+0.005

We add all the numbers together, and all the variables

x^2-0.15x+0.005

Back to the equation:

+(x^2-0.15x+0.005)


We get rid of parentheses

18x^2+x^2-0.15x+0.005

We add all the numbers together, and all the variables

19x^2-0.15x+0.005

Back to the equation:

-(19x^2-0.15x+0.005)


We get rid of parentheses

-19x^2+0.15x-0.005=0

a = -19; b = 0.15; c = -0.005;
Δ = b2-4ac
Δ = 0.152-4·(-19)·(-0.005)
Δ = -0.3575
Delta is less than zero, so there is no solution for the equation
