180=m2

Solution for 180=m2 equation:

180=m2

We move all terms to the left:

180-(m2)=0

We add all the numbers together, and all the variables

-1m^2+180=0

a = -1; b = 0; c = +180;
Δ = b2-4ac
Δ = 02-4·(-1)·180
Δ = 720
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{720}=\sqrt{144*5}=\sqrt{144}*\sqrt{5}=12\sqrt{5}$
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-12\sqrt{5}}{2*-1}=\frac{0-12\sqrt{5}}{-2}
=-\frac{12\sqrt{5}}{-2}
=-\frac{6\sqrt{5}}{-1}
$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+12\sqrt{5}}{2*-1}=\frac{0+12\sqrt{5}}{-2}
=\frac{12\sqrt{5}}{-2}
=\frac{6\sqrt{5}}{-1}
