1.5t^2+12t=0

Solution for 1.5t^2+12t=0 equation:

1.5t^2+12t=0

a = 1.5; b = 12; c = 0;
Δ = b2-4ac
Δ = 122-4·1.5·0
Δ = 144
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{144}=12$
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(12)-12}{2*1.5}=\frac{-24}{3}
=-8
$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(12)+12}{2*1.5}=\frac{0}{3}
=0
