all right, we want to know when is the square root of four X? It was 12 riel. Well, again. We're in square roots. Square roots are only riel. When were squaring positive. Number are a number greater than or equal to zero. Let's take this over to the idea that we want. Um, we want four X Plus 12 to be greater than or equal to zero. And let's solve that. We should subtract 12 to both sides. That leaves us with four X greater than or equal to negative 12 and then to solve for X, we should divide before to both sides. Four x, divided by four is X greater than or equal to negative. 12. Divided by four is three. Whose? Me negative three Eso That could be your solution. If you're writing your solutions and sat builder notation, you may be asked to write solutions and interval notation, and this is just another way to say X is greater than or equal to negative three. By saying all solution for all values make this riel when it X is negative, three included all the way up to infinity
