Solution for 4x^2-18x-122=0 equation:



4x^2-18x-122=0
a = 4; b = -18; c = -122;
Δ = b2-4ac
Δ = -182-4·4·(-122)
Δ = 2276
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:
$\sqrt{\Delta}=\sqrt{2276}=\sqrt{4*569}=\sqrt{4}*\sqrt{569}=2\sqrt{569}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-18)-2\sqrt{569}}{2*4}=\frac{18-2\sqrt{569}}{8} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-18)+2\sqrt{569}}{2*4}=\frac{18+2\sqrt{569}}{8} $
