Answer:

5m²-4m-2 = 0

a = 5,b = -4,c = -2

x = -b±√b²-4ac

     ----------------

          2a

x = -(-4)±√(-4)²-4(-5)(-2)

       ----------------------------

                    2(5)

x = 4±√16+50

      ----------------

             10

x = 4±√56

     -----------

        10

x = 4+√56               4-√56

     ----------     or       ----------

          10                      10

         

by simplifying √56 we get

x = 4+4√16               4-4√16

     ----------     or       ----------

          10                      10
