Solve 36x^2-65x+25=0

36x^2-65x+25=0

This factors as

(9x - 5) (4x -5)  = 0

Set both factors to 0    and we get that

9x - 5  = 0                                        and                  4x - 5  =  0

                                           add 5 to both sides

9x = 5                                                                     4x  = 5

divide both sides by 9                                          divide both sides by 4

x = 5/9                                    or                             x =  5/4
