-6t^2+24t+30=0
a = -6; b = 24; c = +30;
Δ = b2-4ac
Δ = 242-4·(-6)·30
Δ = 1296
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{1296}=36$$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(24)-36}{2*-6}=\frac{-60}{-12} =+5 $$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(24)+36}{2*-6}=\frac{12}{-12} =-1 $
