x(2)+5x-19x=-4

Solution for x(2)+5x-19x=-4 equation:

x(2)+5x-19x=-4

We move all terms to the left:

x(2)+5x-19x-(-4)=0

We add all the numbers together, and all the variables

x^2-14x+4=0

a = 1; b = -14; c = +4;
Δ = b2-4ac
Δ = -142-4·1·4
Δ = 180
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{180}=\sqrt{36*5}=\sqrt{36}*\sqrt{5}=6\sqrt{5}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-14)-6\sqrt{5}}{2*1}=\frac{14-6\sqrt{5}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-14)+6\sqrt{5}}{2*1}=\frac{14+6\sqrt{5}}{2}
