3b^2+21b-24=0
a = 3; b = 21; c = -24;
Δ = b2-4ac
Δ = 212-4·3·(-24)
Δ = 729
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{729}=27$$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(21)-27}{2*3}=\frac{-48}{6} =-8 $$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(21)+27}{2*3}=\frac{6}{6} =1 $
