What are the solutions of the equation (x + 2)2 - 2(x + 2) - 15 = 0? Use u substitution to solve. One particular solution is x = 0 y = 0 z = 0 . Two other solutions are x = 3 y = 6 z = 1 and x = 8 y = 9 z = 2 . There is a unique plane in three-dimensional space which passes through the three points with these coordinates and this plane is the set of all points whose coordinates are solutions of the equation . Solution sets The substitution that is needed to solve this Bernoulli equation is ... A set of solutions to the Riccati equation is then given by = + where z is the general solution to the aforementioned linear equation . See also. Linear-quadratic regulator ... Zeev (1975) [1952] Conformal Mapping New York: Dover Publications ISBN 0 -486-61137- X ; Polyanin ... For example taking the statement x + 1 = 0 if x is substituted with 1 this implies 1 + 1 = 2 = 0 which is false which implies that if x + 1 = 0 then x cannot be 1. If x and y are integers rationals or real n...
