What are the inverse operation for the question x^2 +3=12

answer: addition and subtraction: subtraction undoes addition. for example, if you start with 3 and add 4, you get 7. then, when you subtract 4, you undo the original addition and arrive back at 3:

3 + 4 = 7 → 7 – 4 = 3

this idea of inverse operations makes a lot of sense when you look at the number line. on a number line, 3 + 4 means start at 3, up 4. and 7 – 4 means start at 7, down 4. so when you add 4 and then subtract 4, you end up back where you started.

multiplication and division: division undoes multiplication. for example, if you start with 6 and multiply by 2, you get 12. then, when you divide by 2, you undo the original multiplication and arrive back at 6:

6 x 2 = 12 → 12 / 2 = 6

i do not know the answer i am sorry
