14x2-33x-5=0

Solution for 14x2-33x-5=0 equation:

14x^2-33x-5=0

a = 14; b = -33; c = -5;
Δ = b2-4ac
Δ = -332-4·14·(-5)
Δ = 1369
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1369}=37$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-33)-37}{2*14}=\frac{-4}{28}
=-1/7
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-33)+37}{2*14}=\frac{70}{28}
=2+1/2
