Solution for 4x+30x^2=0 equation:



4x+30x^2=0
a = 30; b = 4; c = 0;
Δ = b2-4ac
Δ = 42-4·30·0
Δ = 16
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{16}=4$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-4}{2*30}=\frac{-8}{60} =-2/15 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+4}{2*30}=\frac{0}{60} =0 $
