-14y^2+44y=0

Solution for -14y^2+44y=0 equation:

-14y^2+44y=0

a = -14; b = 44; c = 0;
Δ = b2-4ac
Δ = 442-4·(-14)·0
Δ = 1936
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1936}=44$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(44)-44}{2*-14}=\frac{-88}{-28}
=3+1/7
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(44)+44}{2*-14}=\frac{0}{-28}
=0
