This form is called factored because it uses the factors of a multiplication.
With this form, we can easily identify the points of intersection of the function with the axis.
The factored form of the quadratic function looks like this:
This form is called factored because it uses the factors of a multiplication.
With this form, we can easily identify the points of intersection of the function with the axis.
The factored form of the quadratic function looks like this:
Find the standard representation of the following function
\( f(x)=(x-2)(x+5) \)
Where
and are the intersection points of the parabola with the axis.
In the following way:
Let's see an example of the factored form:
We can determine that:
the intersection points with the axis are:
Notice that, since there is a minus sign in the original form before and , we can deduce that if there is a plus sign before one of them it is negative and, therefore and not .
Find the standard representation of the following function
\( f(x)=(x-6)(x-2) \)
Find the standard representation of the following function
\( f(x)=(x+2)(x-4) \)
Find the standard representation of the following function
\( f(x)=3x(x+4) \)
