9y2+-44y+208=0

Solution for 9y2+-44y+208=0 equation:

9y^2+-44y+208=0

We add all the numbers together, and all the variables

9y^2-44y=0

a = 9; b = -44; c = 0;
Δ = b2-4ac
Δ = -442-4·9·0
Δ = 1936
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1936}=44$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-44)-44}{2*9}=\frac{0}{18}
=0
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-44)+44}{2*9}=\frac{88}{18}
=4+8/9
