There is a point P (m, n) on the image of the inverse scale function y = K / x, whose coordinates are two roots of the quadratic equation T2 (square) - 3T + k = 0 with respect to t And the distance from P to the origin is the root sign 5 How to get m + n = 3 How to get m + n = 3 How to get m + n = 3 How to get m + n = 3 How to get m + n = 3

There is a point P (m, n) on the image of the inverse scale function y = K / x, whose coordinates are two roots of the quadratic equation T2 (square) - 3T + k = 0 with respect to t
∴mn=k m+n=3
If the distance from P to the origin is root sign 5, then m ^ 2 + N2 = 5 = (M + n) ^ 2-2mn = 9-2k = 5K = 2
The analytic expression of the inverse scale function is y = 2 / X
The sum of the relationship between root and coefficient = - B / a = - (- 3) = 3
