2y^2-1250=0

Solution for 2y^2-1250=0 equation:

2y^2-1250=0

a = 2; b = 0; c = -1250;
Δ = b2-4ac
Δ = 02-4·2·(-1250)
Δ = 10000
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{10000}=100$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-100}{2*2}=\frac{-100}{4}
=-25
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+100}{2*2}=\frac{100}{4}
=25
