10x*x=230,4

Solution for 10x*x=230,4 equation:

10x*x=230.4

We move all terms to the left:

10x*x-(230.4)=0

We add all the numbers together, and all the variables

10x*x-230.4=0

Wy multiply elements

10x^2-230.4=0

a = 10; b = 0; c = -230.4;
Δ = b2-4ac
Δ = 02-4·10·(-230.4)
Δ = 9216
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{9216}=96$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-96}{2*10}=\frac{-96}{20}
=-4+4/5
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+96}{2*10}=\frac{96}{20}
=4+4/5
