12n^2-51n+45=0
a = 12; b = -51; c = +45;
Δ = b2-4ac
Δ = -512-4·12·45
Δ = 441
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{441}=21$$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-51)-21}{2*12}=\frac{30}{24} =1+1/4 $$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-51)+21}{2*12}=\frac{72}{24} =3 $
