Solution for -3y^2+3*61y+61*62=0 equation:

-3y^2+3*61y+61*62=0

We add all the numbers together, and all the variables

-3y^2+3*61y+3782=0

Wy multiply elements

-3y^2+183y+3782=0

a = -3; b = 183; c = +3782;
Δ = b2-4ac
Δ = 1832-4·(-3)·3782
Δ = 78873
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(183)-\sqrt{78873}}{2*-3}=\frac{-183-\sqrt{78873}}{-6}
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(183)+\sqrt{78873}}{2*-3}=\frac{-183+\sqrt{78873}}{-6}
