Solution for 12x^2+4x-320=0 equation:



12x^2+4x-320=0
a = 12; b = 4; c = -320;
Δ = b2-4ac
Δ = 42-4·12·(-320)
Δ = 15376
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{15376}=124$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-124}{2*12}=\frac{-128}{24} =-5+1/3 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+124}{2*12}=\frac{120}{24} =5 $
