Solution for 11x^2+17x=0 equation:



11x^2+17x=0
a = 11; b = 17; c = 0;
Δ = b2-4ac
Δ = 172-4·11·0
Δ = 289
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{289}=17$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(17)-17}{2*11}=\frac{-34}{22} =-1+6/11 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(17)+17}{2*11}=\frac{0}{22} =0 $
