m2=17.5

Solution for m2=17.5 equation:

m2=17.5

We move all terms to the left:

m2-(17.5)=0

We add all the numbers together, and all the variables

m^2-17.5=0

a = 1; b = 0; c = -17.5;
Δ = b2-4ac
Δ = 02-4·1·(-17.5)
Δ = 70
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{70}}{2*1}=\frac{0-\sqrt{70}}{2}
=-\frac{\sqrt{}}{2}
$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{70}}{2*1}=\frac{0+\sqrt{70}}{2}
=\frac{\sqrt{}}{2}
