0.3333h^2-3.3333h+8=0

Solution for 0.3333h^2-3.3333h+8=0 equation:

0.3333h^2-3.3333h+8=0

a = 0.3333; b = -3.3333; c = +8;
Δ = b2-4ac
Δ = -3.33332-4·0.3333·8
Δ = 0.44528889
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-3.3333)-\sqrt{0.44528889}}{2*0.3333}=\frac{3.3333-\sqrt{0.44528889}}{0.6666}
$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-3.3333)+\sqrt{0.44528889}}{2*0.3333}=\frac{3.3333+\sqrt{0.44528889}}{0.6666}
