Answer:
A, C, E
Step-by-step explanation:
By analyzing the graph, we can see that the roots are and
.
We now want to find all equations of the form .
This immediately gives C as 1 answer.
We can expand our equation to find other possible solutions!
By the FOIL method:
We can then divide both sides of the equation to find that , so A is another answer.
We can complete the square on to find the last possible solution.
.
We can then multiply both sides of the equation by to find that
, so E is the last answer.
The proof that the other answers don't work is left as an exercise.
So, the answers are A, C, and E, and we're done!
