-12=0.5x(x+8)

Solution for -12=0.5x(x+8) equation:

-12=0.5x(x+8)

We move all terms to the left:

-12-(0.5x(x+8))=0


We calculate terms in parentheses: -(0.5x(x+8)), so:

0.5x(x+8)

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-x-12=0

We add all the numbers together, and all the variables

-1x^2-1x-12=0

a = -1; b = -1; c = -12;
Δ = b2-4ac
Δ = -12-4·(-1)·(-12)
Δ = -47
Delta is less than zero, so there is no solution for the equation
