9x^2+61x-180=0
a = 9; b = 61; c = -180;
Δ = b2-4ac
Δ = 612-4·9·(-180)
Δ = 10201
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{10201}=101$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(61)-101}{2*9}=\frac{-162}{18} =-9 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(61)+101}{2*9}=\frac{40}{18} =2+2/9 $
