X-12=0.5x(x-4)

Solution for X-12=0.5x(x-4) equation:

X-12=0.5X(X-4)

We move all terms to the left:

X-12-(0.5X(X-4))=0


We calculate terms in parentheses: -(0.5X(X-4)), so:

0.5X(X-4)

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-X-12=0

We add all the numbers together, and all the variables

-1X^2-12=0

a = -1; b = 0; c = -12;
Δ = b2-4ac
Δ = 02-4·(-1)·(-12)
Δ = -48
Delta is less than zero, so there is no solution for the equation
