a = 24; b = 46; c = +21;
Δ = b2-4ac
Δ = 462-4·24·21
Δ = 100
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{100}=10$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(46)-10}{2*24}=\frac{-56}{48} =-1+1/6 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(46)+10}{2*24}=\frac{-36}{48} =-3/4 $
