Answer: Trinomials often (but not always!) have the form x2 + bx + c. ... So, how do you get from 6x2 + 2x – 20 to (2x + 4)(3x −5)? Let's take a look. Factoring Trinomials
Step-by-step explanation:
Answer:
Option A. -6.5
Step-by-step explanation:
we have

Solve for r
That means ---> isolate the variable r
Combine like terns left side of the equation

Divide by 0.5 both sides


I have the same question on a test I'm taking thanks
The vertex form needed is :

Given the equation:

The vertex form of
is given by:

Here, (h,k) is the vertex of the parabola equation given.
Conversion will go like this:

This is the resultant vertex form.
Thus the vertex form needed is :
