12x2*12=25x

Solution for 12x2*12=25x equation:

12x^2*12=25x

We move all terms to the left:

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

Wy multiply elements

144x^2-25x=0

a = 144; b = -25; c = 0;
Δ = b2-4ac
Δ = -252-4·144·0
Δ = 625
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{625}=25$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-25)-25}{2*144}=\frac{0}{288}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-25)+25}{2*144}=\frac{50}{288}
=25/144
