Best ResponseYou've already chosen the best response.1i just showed you. [: i wrote x squared as x^2. x^2 9 = 0 > add 9 on both sides so that it becomes x^2 = 9. to check the answer i gave, just solve 3^2, or 3 * 3, and you'll get 9. so the answer is ±3. or do you have to graph it as well?

Best ResponseYou've already chosen the best response.0@miicchi found the answer. every square root has two answer. \[x ^{2} = 9\] \[x = \sqrt{9}\] x = \[\pm 3\] x = 3 or x = 3 got it?
