9x^2-36x-288=0
a = 9; b = -36; c = -288;
Δ = b2-4ac
Δ = -362-4·9·(-288)
Δ = 11664
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{11664}=108$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-36)-108}{2*9}=\frac{-72}{18} =-4 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-36)+108}{2*9}=\frac{144}{18} =8 $
