Answer:

4(x+3.5)^{2}=0

Step-by-step explanation:

we have

4x^{2}+28x+49=0

step 1

Group terms that contain the same variable, and move the constant to the opposite side of the equation

(4x^{2}+28x)=-49

step 2

Factor the leading coefficient

4(x^{2}+7x)=-49

step 3

Complete the square. Remember to balance the equation by adding the same constants to each side

4(x^{2}+7x+3.5^2)=-49+(3.5^2)(4)

4(x^{2}+7x+12.25)=0

step 4

Rewrite as perfect squares

4(x+3.5)^{2}=0

An Animal's Perspective

Have you ever wondered what it would be like to see the world from the perspective of a bird or another animal? Imagine that you were given the opportunity to spend time as an animal.

Write a short story that describes your time as a bird or another animal. Include descriptive details that explain how you became an animal and what you decide to do.

As you write, remember your essay will be scored based on how well you:

develop a multi-paragraph response to the assigned topic that clearly communicates the purpose of your story to the audience.

describe the characters, setting, and conflict using meaningful sensory descriptions and details that enable the reader to visualize the experiences in your narrative.

organize your story in a clear and logical manner, including an introduction, body, and conclusion.

use well-structured sentences and language that are appropriate for your audience.

edit your work to conform to the conventions of standard American English.

Use any of the tools available to you, such as the Checklist, Spellchecker, or Graphic Organizer.
