72h^2-2=0
a = 72; b = 0; c = -2;
Δ = b2-4ac
Δ = 02-4·72·(-2)
Δ = 576
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}$$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{576}=24$$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-24}{2*72}=\frac{-24}{144} =-1/6 $$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+24}{2*72}=\frac{24}{144} =1/6 $
