x^2-1.333x+0.063=0

Solution for x^2-1.333x+0.063=0 equation:

x^2-1.333x+0.063=0

a = 1; b = -1.333; c = +0.063;
Δ = b2-4ac
Δ = -1.3332-4·1·0.063
Δ = 1.524889
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{-(-1.333)-\sqrt{1.524889}}{2*1}=\frac{1.333-\sqrt{1.524889}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1.333)+\sqrt{1.524889}}{2*1}=\frac{1.333+\sqrt{1.524889}}{2}
