122=2a*2a

Solution for 122=2a*2a equation:

122=2a*2a

We move all terms to the left:

122-(2a*2a)=0

We add all the numbers together, and all the variables

-(+2a*2a)+122=0

We get rid of parentheses

-2a*2a+122=0

Wy multiply elements

-4a^2+122=0

a = -4; b = 0; c = +122;
Δ = b2-4ac
Δ = 02-4·(-4)·122
Δ = 1952
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{1952}=\sqrt{16*122}=\sqrt{16}*\sqrt{122}=4\sqrt{122}$
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{122}}{2*-4}=\frac{0-4\sqrt{122}}{-8}
=-\frac{4\sqrt{122}}{-8}
=-\frac{\sqrt{122}}{-2}
$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{122}}{2*-4}=\frac{0+4\sqrt{122}}{-8}
=\frac{4\sqrt{122}}{-8}
=\frac{\sqrt{122}}{-2}
