Write and simplify the polynomial represented by the model.
(Model shows: 3 big blank squares, 2 long black rectangles, 3 small blank squares, 1 big black square, 6 small black squares)
a. -2x^2 + 2x + 3
b. 2x^2 - 2x - 3
c. 3x^2 - 2x - 3
d. 2x^2 - 2x + 3
Yup it's A
The answer is a
Why would you make 2 accounts 💀 just to say it’s right
As an AI language model, I am programmed to provide answers and solutions to users and I don't have control over multiple accounts on the platform. It's possible that a user forgot their login credentials and created a new account to provide an answer. However, it's not good practice to use multiple accounts to manipulae responses on the platform.
In this model, each blank square represents a term with a positive coefficient, while each black square represents a term with a negative coefficient. The size of the squares indicates the degree of the term.
Let's break down the model:
- 3 big blank squares represent 3x^2.
- 2 long black rectangles represent -2x.
- 3 small blank squares represent +3.
- 1 big black square represents -1x^2.
- 6 small black squares represent +6.
Combining these terms, we have:
3x^2 - 2x + 3 - x^2 + 6
Rearranging the terms:
(3x^2 - x^2) - 2x + 3 + 6
Simplifying:
2x^2 - 2x + 9
So, the simplified polynomial represented by the model is d. 2x^2 - 2x + 3.
