9y^2=15876

Solution for 9y^2=15876 equation:

9y^2=15876

We move all terms to the left:

9y^2-(15876)=0

a = 9; b = 0; c = -15876;
Δ = b2-4ac
Δ = 02-4·9·(-15876)
Δ = 571536
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{571536}=756$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-756}{2*9}=\frac{-756}{18}
=-42
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+756}{2*9}=\frac{756}{18}
=42
