g^2=0.7

Solution for g^2=0.7 equation:

g^2=0.7

We move all terms to the left:

g^2-(0.7)=0

We add all the numbers together, and all the variables

g^2-0.7=0

a = 1; b = 0; c = -0.7;
Δ = b2-4ac
Δ = 02-4·1·(-0.7)
Δ = 2.8
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$g_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$g_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$g_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{2.8}}{2*1}=\frac{0-\sqrt{2.8}}{2}
=-\frac{\sqrt{}}{2}
$
$g_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{2.8}}{2*1}=\frac{0+\sqrt{2.8}}{2}
=\frac{\sqrt{}}{2}
