12x2-10=25

Solution for 12x2-10=25 equation:

12x^2-10=25

We move all terms to the left:

12x^2-10-(25)=0

We add all the numbers together, and all the variables

12x^2-35=0

a = 12; b = 0; c = -35;
Δ = b2-4ac
Δ = 02-4·12·(-35)
Δ = 1680
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:

$\sqrt{\Delta}=\sqrt{1680}=\sqrt{16*105}=\sqrt{16}*\sqrt{105}=4\sqrt{105}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{105}}{2*12}=\frac{0-4\sqrt{105}}{24}
=-\frac{4\sqrt{105}}{24}
=-\frac{\sqrt{105}}{6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{105}}{2*12}=\frac{0+4\sqrt{105}}{24}
=\frac{4\sqrt{105}}{24}
=\frac{\sqrt{105}}{6}
