Solution for 14x^2-22x=0 equation:



14x^2-22x=0
a = 14; b = -22; c = 0;
Δ = b2-4ac
Δ = -222-4·14·0
Δ = 484
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{484}=22$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-22)-22}{2*14}=\frac{0}{28} =0 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-22)+22}{2*14}=\frac{44}{28} =1+4/7 $
