Question

What is the benefit of using the factored form of a quadratic? aThe factored form gives the vertex of the parabola bThe factored form gives the minimum of the parabola cThe factored form gives the maximum of the parabola dThe factored form gives the zeros of the parabola

Answer 1

Quadratic functions f(x) can be written in three forms.

Factored form, the product of a constant and two linear terms:

$a.(x-p).(x-q)\text{ or }a(x-p)^2$

The parameters p and q are the roots of the function (the x-intercepts of the graph y=f(x)). Converting a quadratic function to factored form is called factoring.

Hence, The factored form gives the zeros of the parabola

The correct option is D
