x2=900x=

Solution for x2=900x= equation:

x2=900x=

We move all terms to the left:

x2-(900x)=0

We add all the numbers together, and all the variables

x^2-900x=0

a = 1; b = -900; c = 0;
Δ = b2-4ac
Δ = -9002-4·1·0
Δ = 810000
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{810000}=900$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-900)-900}{2*1}=\frac{0}{2}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-900)+900}{2*1}=\frac{1800}{2}
=900
