The equation based on the information given will be 2x⁴ + 9x³ - x⁴ - 36x - 16 = 0
<h3>How to illustrate the error?</h3>
It should be noted that the information is simply to compute the value properly. This will go thus:
(x + 4)(x + 2)(2x + 1)(x - 2) = 0.
She multiplied (x + 2)(x - 2) correctly and got x² - 4.
She then made a mistake in multiplying (x + 4)(2x ,+ 1).
Therefore, the second step should be (x² - 4)(2x² + 9x + 4).
The next step will be:
2x⁴ + 9x³ + 4x² - 8x⁴ - 36x - 16 = 0
Therefore, the equation based on the information given will be 2x⁴ + 9x³ - x⁴ - 36x - 16 = 0

Step-by-step explanation:
Answer:
Hence the each cheese piece weight equal to 0.3125 pounds
Step-by-step explanation:
Given;
5 pound of cheese block cut down into 16 pieces
To Find:
How much does each wedge of each cheese weigh
Solution:
Now each cheese weigh as follows:
<em>16 cheese pieces of ideal size are considered here so</em>
<em>16 piece equally contribute the the total weight of 5 pounds.</em>
So 5 pound in divided into 16 pieces
i.e 5/16=0.3125 pound per pieces
Hence the each cheese piece weight equal to 0.3125 pounds
i.e Each cheese piece is about 6.25 % of total weight i.e (6.25*16=100 %)
