3m^2-8m-115=0
a = 3; b = -8; c = -115;
Δ = b2-4ac
Δ = -82-4·3·(-115)
Δ = 1444
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{1444}=38$$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-8)-38}{2*3}=\frac{-30}{6} =-5 $$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-8)+38}{2*3}=\frac{46}{6} =7+2/3 $
