144=10x^2

Solution for 144=10x^2 equation:

144=10x^2

We move all terms to the left:

144-(10x^2)=0

a = -10; b = 0; c = +144;
Δ = b2-4ac
Δ = 02-4·(-10)·144
Δ = 5760
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:

$\sqrt{\Delta}=\sqrt{5760}=\sqrt{576*10}=\sqrt{576}*\sqrt{10}=24\sqrt{10}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-24\sqrt{10}}{2*-10}=\frac{0-24\sqrt{10}}{-20}
=-\frac{24\sqrt{10}}{-20}
=-\frac{6\sqrt{10}}{-5}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+24\sqrt{10}}{2*-10}=\frac{0+24\sqrt{10}}{-20}
=\frac{24\sqrt{10}}{-20}
=\frac{6\sqrt{10}}{-5}
