12x2+12x-10=0

Solution for 12x2+12x-10=0 equation:

12x^2+12x-10=0

a = 12; b = 12; c = -10;
Δ = b2-4ac
Δ = 122-4·12·(-10)
Δ = 624
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:

$\sqrt{\Delta}=\sqrt{624}=\sqrt{16*39}=\sqrt{16}*\sqrt{39}=4\sqrt{39}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(12)-4\sqrt{39}}{2*12}=\frac{-12-4\sqrt{39}}{24}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(12)+4\sqrt{39}}{2*12}=\frac{-12+4\sqrt{39}}{24}
