Best ResponseYou've already chosen the best response.1may be just try solving it : \(x^2+3=0 \implies x^2=3 \implies \cdots \)

Best ResponseYou've already chosen the best response.0Okay can you explain to me how to solve it. I came uo with x=6 so one solution but i dont know if thats correct

Best ResponseYou've already chosen the best response.1plugin \(x=6\) does it make the given equation true ?

Best ResponseYou've already chosen the best response.1x^2 + 3 = 0 6^2 + 3 = 0 36 + 3 = 0 39 = 0 which is clearly false, so nope, x=6 is not a solution.

Best ResponseYou've already chosen the best response.0What about a square root of negative 3? Does such thing exist?

Best ResponseYou've already chosen the best response.0I think there is no solution right?

Best ResponseYou've already chosen the best response.0What if I try putting the negative sign before the bracket surrounding square root of 3?

Best ResponseYou've already chosen the best response.0Like (sqrt(3)) Probably I am wrong.

Best ResponseYou've already chosen the best response.0Nah forget it I don't think that even exists.

Best ResponseYou've already chosen the best response.0So yeah, I think x would have to be of square root value but with the negative sign I think that makes the equation unsolvable. Is that correct?

Best ResponseYou've already chosen the best response.1depends on the set we are solving over but no sqrt(3) doesn't equal sqrt(3) sqrt(3) is imaginary while sqrt(3) is real

Best ResponseYou've already chosen the best response.0Right. Imaginary root shuold be used as the solution. So I belive minus square root of three might be more relevant? Forgive me if I am wrong.

Best ResponseYou've already chosen the best response.0So that's the full solution for x apparently. @abriannaridley I guess that's your take home message from todayXD

Best ResponseYou've already chosen the best response.0okay so im not 100% if this is right but there is only solution to that problem? @freckles

Best ResponseYou've already chosen the best response.0Yes lol! should've just said no solution

Best ResponseYou've already chosen the best response.0Find the xintercepts of the graph of the equation: y = x2  3x + 2 im not sure how to do this one either should i just post it as a new question?

Best ResponseYou've already chosen the best response.1xintercepts can found by setting y to 0 and solve for x

Best ResponseYou've already chosen the best response.1but you can post a question I guess if you have trouble solving 0=x^23x+2

Best ResponseYou've already chosen the best response.1sry for the delay, here it is : ``` A foreman is yelling down into an excavation : "How many of you men down there ?" the reply came back, "three." and he said "Okay, half of you come on up." ```

Best ResponseYou've already chosen the best response.1that joke refers to solving the equation \(2x=3\). does it really have a solution ? If it has a solution, what does it represent ?
