-60X^2+30x=0

Solution for -60X^2+30x=0 equation:

-60X^2+30X=0

a = -60; b = 30; c = 0;
Δ = b2-4ac
Δ = 302-4·(-60)·0
Δ = 900
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{900}=30$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(30)-30}{2*-60}=\frac{-60}{-120}
=1/2
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(30)+30}{2*-60}=\frac{0}{-120}
=0
