16t^2-50t-36=0

Solution for 16t^2-50t-36=0 equation:

16t^2-50t-36=0

a = 16; b = -50; c = -36;
Δ = b2-4ac
Δ = -502-4·16·(-36)
Δ = 4804
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{4804}=\sqrt{4*1201}=\sqrt{4}*\sqrt{1201}=2\sqrt{1201}$
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-50)-2\sqrt{1201}}{2*16}=\frac{50-2\sqrt{1201}}{32}
$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-50)+2\sqrt{1201}}{2*16}=\frac{50+2\sqrt{1201}}{32}
