      2x^2 -8x +10 = 0  >  a = 2,  b = -8,  c = 10


      quadratic formula


      PLUG IN THE VALUES FOR: a, b, c


      x = -(-8) + or - square root of  (-8)^2 - 4(2)(10) over 2(2)


      x = 8 + or -  square root of 64 - 80 over  4


      x = 8 + or - square root of  -16 over  4


      Note: -16 has a square root of 4i


      Answer: x = 8 + 4i over4,  8 - 4i over 4


      I think this is right!
