Solution for 1.5x^2+3x-8=0 equation: 



1.5x^2+3x-8=0

a = 1.5; b = 3; c = -8;
Δ = b2-4ac
Δ = 32-4·1.5·(-8)
Δ = 57
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(3)-\sqrt{57}}{2*1.5}=\frac{-3-\sqrt{57}}{3}
$


$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+\sqrt{57}}{2*1.5}=\frac{-3+\sqrt{57}}{3}
$
