-6a^2+24a+126=0
a = -6; b = 24; c = +126;
Δ = b2-4ac
Δ = 242-4·(-6)·126
Δ = 3600
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{3600}=60$$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(24)-60}{2*-6}=\frac{-84}{-12} =+7 $$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(24)+60}{2*-6}=\frac{36}{-12} =-3 $
