x=(0.15x)(0.10-x)

Solution for x=(0.15x)(0.10-x) equation:

x=(0.15x)(0.10-x)

We move all terms to the left:

x-((0.15x)(0.10-x))=0

We add all the numbers together, and all the variables

x-((+0.15x)(-1x+0.1))=0

We multiply parentheses ..

-((+0x^2+0x))+x=0


We calculate terms in parentheses: -((+0x^2+0x)), so:

(+0x^2+0x)

We get rid of parentheses

0x^2+0x

We add all the numbers together, and all the variables

x^2+x

Back to the equation:

-(x^2+x)


We add all the numbers together, and all the variables

x-(x^2+x)=0

We get rid of parentheses

-x^2+x-x=0

We add all the numbers together, and all the variables

-1x^2=0

a = -1; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-1)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
