-4.79x^2-2.33x+2.01=0

Solution for -4.79x^2-2.33x+2.01=0 equation:

-4.79x^2-2.33x+2.01=0

a = -4.79; b = -2.33; c = +2.01;
Δ = b2-4ac
Δ = -2.332-4·(-4.79)·2.01
Δ = 43.9405
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{-(-2.33)-\sqrt{43.9405}}{2*-4.79}=\frac{2.33-\sqrt{43.9405}}{-9.58}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-2.33)+\sqrt{43.9405}}{2*-4.79}=\frac{2.33+\sqrt{43.9405}}{-9.58}
