12-m2=-34

Solution for 12-m2=-34 equation:

12-m2=-34

We move all terms to the left:

12-m2-(-34)=0

We add all the numbers together, and all the variables

-1m^2+46=0

a = -1; b = 0; c = +46;
Δ = b2-4ac
Δ = 02-4·(-1)·46
Δ = 184
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:

$\sqrt{\Delta}=\sqrt{184}=\sqrt{4*46}=\sqrt{4}*\sqrt{46}=2\sqrt{46}$
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{46}}{2*-1}=\frac{0-2\sqrt{46}}{-2}
=-\frac{2\sqrt{46}}{-2}
=-\frac{\sqrt{46}}{-1}
$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{46}}{2*-1}=\frac{0+2\sqrt{46}}{-2}
=\frac{2\sqrt{46}}{-2}
=\frac{\sqrt{46}}{-1}
