2.25x2-4x=0

Solution for 2.25x2-4x=0 equation:

2.25x^2-4x=0

a = 2.25; b = -4; c = 0;
Δ = b2-4ac
Δ = -42-4·2.25·0
Δ = 16
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{16}=4$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-4)-4}{2*2.25}=\frac{0}{4.5}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-4)+4}{2*2.25}=\frac{8}{4.5}
=1+2.3333333333333/3
