X=0.5x(x+2)

Solution for X=0.5x(x+2) equation:

X=0.5X(X+2)

We move all terms to the left:

X-(0.5X(X+2))=0


We calculate terms in parentheses: -(0.5X(X+2)), so:

0.5X(X+2)

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=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
