104=x(x-3)/2

Solution for 104=x(x-3)/2 equation:

104=x(x-3)/2

We move all terms to the left:

104-(x(x-3)/2)=0

We multiply all the terms by the denominator


-(x(x-3)+104*2)=0


We calculate terms in parentheses: -(x(x-3)+104*2), so:

x(x-3)+104*2

We add all the numbers together, and all the variables

x(x-3)+208

We multiply parentheses

x^2-3x+208

Back to the equation:

-(x^2-3x+208)


We get rid of parentheses

-x^2+3x-208=0

We add all the numbers together, and all the variables

-1x^2+3x-208=0

a = -1; b = 3; c = -208;
Δ = b2-4ac
Δ = 32-4·(-1)·(-208)
Δ = -823
Delta is less than zero, so there is no solution for the equation
