Solution for 1.5x^2-8x-6=0 equation:



1.5x^2-8x-6=0
a = 1.5; b = -8; c = -6;
Δ = b2-4ac
Δ = -82-4·1.5·(-6)
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{-(-8)-10}{2*1.5}=\frac{-2}{3} =-2/3 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-8)+10}{2*1.5}=\frac{18}{3} =6 $
