Solution for 4v2+4v-120=0 equation:



4v^2+4v-120=0
a = 4; b = 4; c = -120;
Δ = b2-4ac
Δ = 42-4·4·(-120)
Δ = 1936
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1936}=44$
$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-44}{2*4}=\frac{-48}{8} =-6 $
$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+44}{2*4}=\frac{40}{8} =5 $
