6x^2+15x-99=0
a = 6; b = 15; c = -99;
Δ = b2-4ac
Δ = 152-4·6·(-99)
Δ = 2601
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{2601}=51$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(15)-51}{2*6}=\frac{-66}{12} =-5+1/2 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(15)+51}{2*6}=\frac{36}{12} =3 $
