Solution for 3k^2+5k-4=0 equation: 



3k^2+5k-4=0

a = 3; b = 5; c = -4;
Δ = b2-4ac
Δ = 52-4·3·(-4)
Δ = 73
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(5)-\sqrt{73}}{2*3}=\frac{-5-\sqrt{73}}{6}
$


$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5)+\sqrt{73}}{2*3}=\frac{-5+\sqrt{73}}{6}
$
