9u^2+77u-36=0
a = 9; b = 77; c = -36;
Δ = b2-4ac
Δ = 772-4·9·(-36)
Δ = 7225
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$u_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$u_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{7225}=85$$u_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(77)-85}{2*9}=\frac{-162}{18} =-9 $$u_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(77)+85}{2*9}=\frac{8}{18} =4/9 $
