36y^2=7

Solution for 36y^2=7 equation:

36y^2=7

We move all terms to the left:

36y^2-(7)=0

a = 36; b = 0; c = -7;
Δ = b2-4ac
Δ = 02-4·36·(-7)
Δ = 1008
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{1008}=\sqrt{144*7}=\sqrt{144}*\sqrt{7}=12\sqrt{7}$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-12\sqrt{7}}{2*36}=\frac{0-12\sqrt{7}}{72}
=-\frac{12\sqrt{7}}{72}
=-\frac{\sqrt{7}}{6}
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+12\sqrt{7}}{2*36}=\frac{0+12\sqrt{7}}{72}
=\frac{12\sqrt{7}}{72}
=\frac{\sqrt{7}}{6}
