-360x^2+3240x=0

Solution for -360x^2+3240x=0 equation:

-360x^2+3240x=0

a = -360; b = 3240; c = 0;
Δ = b2-4ac
Δ = 32402-4·(-360)·0
Δ = 10497600
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{10497600}=3240$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(3240)-3240}{2*-360}=\frac{-6480}{-720}
=+9
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3240)+3240}{2*-360}=\frac{0}{-720}
=0
