Solution for 13x-4x^2=0 equation: 



13x-4x^2=0

a = -4; b = 13; c = 0;
Δ = b2-4ac
Δ = 132-4·(-4)·0
Δ = 169
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{169}=13$


$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(13)-13}{2*-4}=\frac{-26}{-8}
=3+1/4
$


$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(13)+13}{2*-4}=\frac{0}{-8}
=0
$
