There are three methods that can be used to solve for the solution of an equation in quadratic form. These are:
1. By factoring
2. By completing the square
3. By using the quadratic formula.
For example: $ x^2-2x+1=0$
By factoring:
$(x-1)^2=0$
$x=1$
By completing the square:
$ x^2-2x=-1$
$ x^2-2x=-1$
$ x^2-2x+1=-1+1$
$ x^2-2x+1=0$
$ (x-1)^2=0$
$x=1$
By using the quadratic formula:
$a=1$, $b=-2$, $c=1$
$x = \frac{-b±\sqrt{b^2-4ac}}{2a}$
$x = \frac{-(-2)±\sqrt{(-2)^2-(4⋅1⋅1}}{2⋅1}$
$x = \frac{2±\sqrt{4-4}}{2}$
$x=1$
