Solution for 7y2+29y=0 equation:



7y^2+29y=0
a = 7; b = 29; c = 0;
Δ = b2-4ac
Δ = 292-4·7·0
Δ = 841
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{841}=29$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(29)-29}{2*7}=\frac{-58}{14} =-4+1/7 $
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(29)+29}{2*7}=\frac{0}{14} =0 $
