 Hello and welcome to the session. In this session we will discuss a question which says that draw a graph of the quadratic function x square plus x minus 2, hence find the roots. Now, we will start with the solution. Here, let y is equal to x square plus x minus 2. Now, let us form a set of pairs of values for x and y and for this we have made a table. Now, we have taken y is equal to x square plus x minus 2. Now, for x is equal to 0, y is equal to 0 plus 0 minus 2 that is equal to minus 2. So, for x is equal to 0, y is equal to minus 2. Now, for x is equal to 1, y is equal to 1 square plus 1 minus 2 that is equal to 1 plus 1 minus 2 which is equal to 0. So, for x is equal to 1, y is equal to 0. Now, for x is equal to 2, y is equal to 2 square plus 2 minus 2 which is equal to 4 plus 2 minus 2 which is equal to 4. So, for x is equal to 2, y is equal to 4. Now, for x is equal to 3, y is equal to 3 square plus 3 minus 2 which is 9 plus 3 minus 2 which is further equal to 10. So, for x is equal to 3, y is equal to 10. Now, for x is equal to minus 1, y is equal to minus 1 whole square plus of minus 1 minus 2 which is equal to 1 minus 1 minus 2 which is equal to minus 2. So, for x is equal to minus 1, y is equal to minus 2. Now, for x is equal to minus 2, y is equal to minus 2 whole square plus of minus 2 minus 2 which is equal to 4 minus 2 minus 2 which is equal to 0. So, for x is equal to minus 2, y is equal to 0. Now, for x is equal to minus 3, y is equal to minus 3 whole square plus of minus 3 minus 2 which is equal to 9 minus 3 minus 2 which is equal to 4. So, for x is equal to minus 3, y is equal to 4. Now, for x is equal to minus 4, y is equal to minus 4 whole square plus of minus 4 minus 2 which is equal to 16 minus 4 minus 2 which is equal to 10. So, for x is equal to minus 4, y is equal to 10. Now, we have formed a set of pairs of values for x and y. Now, we will plot these points on the graph. The coordinates of first point are 0 minus 2. So, this is the point 0 minus 2 on the graph. Coordinates of next point are 1, 0. So, this is the point 1, 0 on the graph. The coordinates of next point are 2, 4. So, this is the point 2, 4 on the graph. Similarly, we will plot all these points on the graph. Now, we have plotted all the points on the graph. Now, by joining all these points, we are getting the graph of the quadratic function. Now, this graph is cutting the x-axis at these points. And the points are minus 2, 0 and 1, 0. So, the graph cuts the x-axis at the points minus 2, 0 and 1, 0. Hence, the required roots are x is equal to minus 2 and 1. So, this is the solution of the given question and that's all for this session. Hope you all have enjoyed the session.
