365000=x(x-3)

Solution for 365000=x(x-3) equation:

365000=x(x-3)

We move all terms to the left:

365000-(x(x-3))=0


We calculate terms in parentheses: -(x(x-3)), so:

x(x-3)

We multiply parentheses

x^2-3x

Back to the equation:

-(x^2-3x)


We get rid of parentheses

-x^2+3x+365000=0

We add all the numbers together, and all the variables

-1x^2+3x+365000=0

a = -1; b = 3; c = +365000;
Δ = b2-4ac
Δ = 32-4·(-1)·365000
Δ = 1460009
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(3)-\sqrt{1460009}}{2*-1}=\frac{-3-\sqrt{1460009}}{-2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+\sqrt{1460009}}{2*-1}=\frac{-3+\sqrt{1460009}}{-2}
