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

Hey there!
First, we'll need to isolate the y variable, meaning that we'll need all of the y's on one side. To do this, we'll need to subtract 8x from both sides. This leaves us with 2y = -8x - 10.
Second, we'll need to get y all by itself, without the 2. To do this, we'll need to divide both sides by 2. This leaves us with y = -4x - 5.
Therefore, your answer is the first option, or the darkest blue box.
Hope this helps!! :)
Answer:
im pretty sure the answer would be 40m
Step-by-step explanation:
<span>Nope. A consistent system is either dependent (both equations represent the same line) or independent. So in an independent system, the lines intersect in exactly one point, which means there is exactly one solution. A dependent system has an infinite number of solutions. An inconsistent system has no solution, so no system of linear equations can have exactly two solutions.</span>
