That's when you right here. So here we're going to find for X in the equation. Three X Square plus 24 is equal to zero. So first thing we're gonna do is that we want to subtract 24 on both sides to get three X square is equal to negative 24 when we divide by three. To get X square is equal to negative eat. And let's take a look on the right here, right here. So we know that one x square is equal to negative one and we want to find for X X is equal to plus or minus I where I is an imaginary number. So here we're going to square root both sides and we know that square Opec's square is equal to the square root of four times the square root of two times the square root of negative one. So when we calculate that comes X is equal to plus minus two squared of two. I
