5,9x^2-2,3x=0

Solution for 5,9x^2-2,3x=0 equation:

5.9x^2-2.3x=0

a = 5.9; b = -2.3; c = 0;
Δ = b2-4ac
Δ = -2.32-4·5.9·0
Δ = 5.29
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{-(-2.3)-\sqrt{5.29}}{2*5.9}=\frac{2.3-\sqrt{5.29}}{11.8}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-2.3)+\sqrt{5.29}}{2*5.9}=\frac{2.3+\sqrt{5.29}}{11.8}
$
