A quadratic equation may be written in several different forms.
1. Standard form
2. Vertex form
3. Intercept form
Let us have a look at how these forms are written
1. Standard form:
This form is best suited when we want to find the roots of the equation using factoring or the quadratic formula.
[tex]y=ax^2+bx+c[/tex]2. Vertex form:
This form is best suited when you want to find out the vertex (highest or lowest point) of the quadratic equation.
[tex]y=a(x-h)^2+k[/tex]3. Intercept form:
[tex]y=a(x-p)(x-q)[/tex]
