(6x+19)x=180
We move all terms to the left:
(6x+19)x-(180)=0
We multiply parentheses
6x^2+19x-180=0
a = 6; b = 19; c = -180;
Δ = b2-4ac
Δ = 192-4·6·(-180)
Δ = 4681
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(19)-\sqrt{4681}}{2*6}=\frac{-19-\sqrt{4681}}{12} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(19)+\sqrt{4681}}{2*6}=\frac{-19+\sqrt{4681}}{12} $
