determiningTheFunctionDomain 15x^2+4x-110=0
a = 15; b = 4; c = -110;
Δ = b2-4ac
Δ = 42-4·15·(-110)
Δ = 6616
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:
$\sqrt{\Delta}=\sqrt{6616}=\sqrt{4*1654}=\sqrt{4}*\sqrt{1654}=2\sqrt{1654}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-2\sqrt{1654}}{2*15}=\frac{-4-2\sqrt{1654}}{30} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+2\sqrt{1654}}{2*15}=\frac{-4+2\sqrt{1654}}{30} $
