5t^2+3t-92=0
a = 5; b = 3; c = -92;
Δ = b2-4ac
Δ = 32-4·5·(-92)
Δ = 1849
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1849}=43$
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(3)-43}{2*5}=\frac{-46}{10} =-4+3/5 $
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+43}{2*5}=\frac{40}{10} =4 $
