y^-17y^2+70y=0

Solution for y^-17y^2+70y=0 equation:

y^-17y^2+70y=0

We add all the numbers together, and all the variables

-17y^2+71y=0

a = -17; b = 71; c = 0;
Δ = b2-4ac
Δ = 712-4·(-17)·0
Δ = 5041
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{5041}=71$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(71)-71}{2*-17}=\frac{-142}{-34}
=4+3/17
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(71)+71}{2*-17}=\frac{0}{-34}
=0
