1=w2/4

Solution for 1=w2/4 equation:

1=w2/4

We move all terms to the left:

1-(w2/4)=0

We add all the numbers together, and all the variables

-(+w2/4)+1=0

We get rid of parentheses

-w2/4+1=0

We multiply all the terms by the denominator


-w2+1*4=0

We add all the numbers together, and all the variables

-1w^2+4=0

a = -1; b = 0; c = +4;
Δ = b2-4ac
Δ = 02-4·(-1)·4
Δ = 16
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

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