144=25x2

Solution for 144=25x2 equation:

144=25x^2

We move all terms to the left:

144-(25x^2)=0

a = -25; b = 0; c = +144;
Δ = b2-4ac
Δ = 02-4·(-25)·144
Δ = 14400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{14400}=120$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-120}{2*-25}=\frac{-120}{-50}
=2+2/5
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+120}{2*-25}=\frac{120}{-50}
=-2+2/5
