Solution for t^2+2t-0.5=0 equation: 



t^2+2t-0.5=0

a = 1; b = 2; c = -0.5;
Δ = b2-4ac
Δ = 22-4·1·(-0.5)
Δ = 6
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-\sqrt{6}}{2*1}=\frac{-2-\sqrt{6}}{2}
$


$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+\sqrt{6}}{2*1}=\frac{-2+\sqrt{6}}{2}
$
