 Hi, and welcome to the session. Let us discuss the following question. The question says, in each of the exercises, 7 to 12, find the equation of the parabola that satisfies the given conditions. Given conditions are coordinates of focus as 6, 0, and directrix is x equals to minus 6. Before solving this question, we should know that if the parabola has voted x at the origin, focus at the point a, 0, and directrix x equals to minus 8, then the equation of parabola is of the form y squared equals to 4ax. This is one of the standard equations of parabola. So keeping this in mind, let's now begin with the solution. We are given that focus of the required parabola is at the point 6, 0, and its directrix is x equals to minus 6. Now clearly, the focus, 6, 0, lies on positive side axis. Axis, the axis of parabola, parabola, opens to the right, like in this figure. If the focus of the parabola is at the point a, 0, and its directrix is x equals to minus 8, then equation of parabola is of the form y squared equals to 4ax. Now here, the coordinates of the focus, that is 6, 0, is in the form, the equation of directrix, that is x equals to minus 6, is in the form of c equals to minus 8. So this implies that equation of required parabola is of the form y squared equals to 4ax. Now here, a is equal to 6, so by putting a as 6 in this equation, we get y squared equals to 4 into 6 into x, and this is equal to 24x. So y squared equals to 24x is the required equation of the parabola. Hence a required answer is, y squared is equal to 24x. This completes the session. Bye, and take care.
