 Hi, I am Deepika here. Welcome you to visit this session. Here I am solving the problem given by Find the distance between the following pair of points a b and minus a minus b So let's start the solution We know that the distance between any two points p x1 y1 and q x2 y2 is given by Pq is equal to under root of x2 minus x1 whole square plus y2 minus y1 whole square it is called the distance formula So we will take the help of this distance formula to solve the question. So let's start the solution let P a b minus b Be the given points by using the distance formula Which is our key idea for this question. We have distance pq is equal to under root of x2 minus x1 whole square that is a plus a square minus a minus y2 minus y1 whole square that is minus b minus b whole square So this is equal to B square equal to equal to plus b square the distance between the points a minus b is twice Under root of a square plus b square. So the answer for this question is 2 plus b square. I hope the question is clear to you By and enjoy yourself
