Wy multiply elements

-1020y^2+5y=0

a = -1020; b = 5; c = 0;
Δ = b2-4ac
Δ = 52-4·(-1020)·0
Δ = 25
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{25}=5$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(5)-5}{2*-1020}=\frac{-10}{-2040}
=1/204
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5)+5}{2*-1020}=\frac{0}{-2040}
=0
