-2t-3/2t-9-16=0

We multiply all the terms by the denominator


-2t*2t-9*2t-16*2t-3=0

Wy multiply elements

-4t^2-18t-32t-3=0

We add all the numbers together, and all the variables

-4t^2-50t-3=0

a = -4; b = -50; c = -3;
Δ = b2-4ac
Δ = -502-4·(-4)·(-3)
Δ = 2452
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:

$\sqrt{\Delta}=\sqrt{2452}=\sqrt{4*613}=\sqrt{4}*\sqrt{613}=2\sqrt{613}$
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-50)-2\sqrt{613}}{2*-4}=\frac{50-2\sqrt{613}}{-8}
$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-50)+2\sqrt{613}}{2*-4}=\frac{50+2\sqrt{613}}{-8}
