Question

What form is this? y = ax^2 + bx+ c Standard Form Vertex Form Intercept Form

Answer 1

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.

`y=ax^2+bx+c`

2. Vertex form:

This form is best suited when you want to find out the vertex (highest or lowest point) of the quadratic equation.

`y=a(x-h)^2+k`

3. Intercept form:

`y=a(x-p)(x-q)`
