Solution for h2-7h=0 equation:

h2-7h=0 We add all the numbers together, and all the variables h^2-7h=0 a = 1; b = -7; c = 0;Δ = b2-4acΔ = -72-4·1·0Δ = 49The delta value is higher than zero, so the equation has two solutionsWe use following formulas to calculate our solutions:$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{49}=7$ $h_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-7)-7}{2*1}=\frac{0}{2} =0 $ $h_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-7)+7}{2*1}=\frac{14}{2} =7 $
