Solution for 3y2+24y+45=0 equation: 



3y^2+24y+45=0

a = 3; b = 24; c = +45;
Δ = b2-4ac
Δ = 242-4·3·45
Δ = 36
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{36}=6$


$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(24)-6}{2*3}=\frac{-30}{6}
=-5
$


$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(24)+6}{2*3}=\frac{-18}{6}
=-3
$
