0.3x-1=0.1x(x+10)

Solution for 0.3x-1=0.1x(x+10) equation:

0.3x-1=0.1x(x+10)

We move all terms to the left:

0.3x-1-(0.1x(x+10))=0


We calculate terms in parentheses: -(0.1x(x+10)), so:

0.1x(x+10)

We multiply 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 get rid of parentheses

-x^2+0.3x-x-1=0

We add all the numbers together, and all the variables

-1x^2-0.7x-1=0

a = -1; b = -0.7; c = -1;
Δ = b2-4ac
Δ = -0.72-4·(-1)·(-1)
Δ = -3.51
Delta is less than zero, so there is no solution for the equation
