Solution for 17f^2+31f=0 equation:



17f^2+31f=0
a = 17; b = 31; c = 0;
Δ = b2-4ac
Δ = 312-4·17·0
Δ = 961
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$f_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$f_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{961}=31$
$f_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(31)-31}{2*17}=\frac{-62}{34} =-1+14/17 $
$f_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(31)+31}{2*17}=\frac{0}{34} =0 $
