Determine the values of
a, b, and c for
the quadratic equation: 
x² – 8x = 0

• 
  a = 1, b = -8, c = 1

• 
  a = 0, b = 8, c = 0

• a = 1, b =-8, c =0

• a = 1, b = 8, c = 0

Determine the values of
a, b, and c for
the quadratic equation: 
2x² – 4x + 5 = 0

• 
  a = 2, b = -4, c = 5

• 
  a = -2, b = -4, c = 5

• a = 2, b = -4, c = -5
