Answer:
The correct answer that you are looking for is the following equations make x = 2 correct: x2 - 4 = 0, 4x2 = 16, and 2(x-2)2 = 0
The following equations make x = -2 correct: x2 = -4, and 3x2+12=0
Explanation:
When finding out if x fits a certain number, there are many things to keep in mind, such as making sure that both sides are equal, making that if x changes the equation is resolved correctly, and also having to solve all the equations, of course.
The strategy that I chose was replacing x with either 2, or -2, and whichever one matched the final result would mean that x does equal that term.
Another strategy that could be more beneficial is solving the equation with step-by-step ideas.
I replaced x as 2 in x2 - 4 = 0, 4x2 = 16, and 2(x-2)2 = 0 and they matched the result.
For the remaining equations that didn't match the result I replaced x with -2 and then they finally matched.
I replaced x as -2 in x2 = -4, and 3x2+12=0 and they matched the result.
If in any shape or form, I was incorrect please inform me and I'll attempt to resolve the issue and see my mistake, sorry if thi was wordy and long.
I hope this was helpful!
