Solution for -14y2+10y=0 equation:



-14y^2+10y=0
a = -14; b = 10; c = 0;
Δ = b2-4ac
Δ = 102-4·(-14)·0
Δ = 100
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{100}=10$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(10)-10}{2*-14}=\frac{-20}{-28} =5/7 $
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(10)+10}{2*-14}=\frac{0}{-28} =0 $
