-9X^2-13X+5=0

a = -9; b = -13; c = +5;
Δ = b2-4ac
Δ = -132-4·(-9)·5
Δ = 349
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-13)-\sqrt{349}}{2*-9}=\frac{13-\sqrt{349}}{-18}
$


$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-13)+\sqrt{349}}{2*-9}=\frac{13+\sqrt{349}}{-18}
$
