15x2=540

Solution for 15x2=540 equation:

15x^2=540

We move all terms to the left:

15x^2-(540)=0

a = 15; b = 0; c = -540;
Δ = b2-4ac
Δ = 02-4·15·(-540)
Δ = 32400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{32400}=180$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-180}{2*15}=\frac{-180}{30}
=-6
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+180}{2*15}=\frac{180}{30}
=6
