3y*y-4,4y-9,6=0

Solution for 3y*y-4,4y-9,6=0 equation:

3y*y-4.4y-9.6=0

We add all the numbers together, and all the variables

-4.4y+3y*y-9.6=0

Wy multiply elements

3y^2-4.4y-9.6=0

a = 3; b = -4.4; c = -9.6;
Δ = b2-4ac
Δ = -4.42-4·3·(-9.6)
Δ = 134.56
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{-(-4.4)-\sqrt{134.56}}{2*3}=\frac{4.4-\sqrt{134.56}}{6}
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-4.4)+\sqrt{134.56}}{2*3}=\frac{4.4+\sqrt{134.56}}{6}
