a = -4; b = 144; c = +1;
Δ = b2-4ac
Δ = 1442-4·(-4)·1
Δ = 20752
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:

$\sqrt{\Delta}=\sqrt{20752}=\sqrt{16*1297}=\sqrt{16}*\sqrt{1297}=4\sqrt{1297}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(144)-4\sqrt{1297}}{2*-4}=\frac{-144-4\sqrt{1297}}{-8}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(144)+4\sqrt{1297}}{2*-4}=\frac{-144+4\sqrt{1297}}{-8}
