Solution for 6X2+24x-15=0 equation:



6X^2+24X-15=0
a = 6; b = 24; c = -15;
Δ = b2-4ac
Δ = 242-4·6·(-15)
Δ = 936
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:
$\sqrt{\Delta}=\sqrt{936}=\sqrt{36*26}=\sqrt{36}*\sqrt{26}=6\sqrt{26}$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(24)-6\sqrt{26}}{2*6}=\frac{-24-6\sqrt{26}}{12} $
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(24)+6\sqrt{26}}{2*6}=\frac{-24+6\sqrt{26}}{12} $
