Solve: 24x^3 -26x^ 2 +9x -1=0.

x = 1/2 , x = 1/4 , x = 1/3

Step-by-step explanation:

Factor the following equation --> 24x^3 — 26x^2 + 9x — 1 = 0

You will get > (2x - 1) (4x - 1) (3x - 1) = 0

Now make all the above expressions = 0 and solve.

2x - 1 = 0                                4x - 1 = 0                                 3x - 1 = 0

   +1    +1                                    +1    +1                                      +1     +1

2x = 1                                          4x = 1                                      3x = 1

/2   /2                                          /4   /4                                      /3    /3

x = 1/2                                           x = 1/4                                     x = 1/3

33

Step-by-step explanation:

The total number of students in seventh grade at Western Middle School = 220

The percent of the students in seventh grade have perfect attendance=15%

Then, the number of students have perfect attendance is given by :

15% of 220

Hence, 33 students have perfect attendance.
