6x^2+10x-787=0

Solution for 6x^2+10x-787=0 equation:

6x^2+10x-787=0

a = 6; b = 10; c = -787;
Δ = b2-4ac
Δ = 102-4·6·(-787)
Δ = 18988
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:

$\sqrt{\Delta}=\sqrt{18988}=\sqrt{4*4747}=\sqrt{4}*\sqrt{4747}=2\sqrt{4747}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(10)-2\sqrt{4747}}{2*6}=\frac{-10-2\sqrt{4747}}{12}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(10)+2\sqrt{4747}}{2*6}=\frac{-10+2\sqrt{4747}}{12}
