18x-35+5x^2=0
a = 5; b = 18; c = -35;
Δ = b2-4ac
Δ = 182-4·5·(-35)
Δ = 1024
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1024}=32$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(18)-32}{2*5}=\frac{-50}{10} =-5 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(18)+32}{2*5}=\frac{14}{10} =1+2/5 $
