  In order to find the sum and product of the roots, we have the following formula:

  Let r and s be the roots of degree 2 trinomial

  r + s = -b/a

  rs = c/a

  where the format of the equation must be in Standard Form:

  ax^2 + bx + c = 0

  We have our equation:

  2x^2 - 11x + 3 = 0

  where a = 2

  b = -11

  c = 3

  By substituting the following values, we can now solve the sum and products of our given equation.

  r + s = -b/a

  = -(-11)/2

  r + s = 11/2

  rs = c/a

  rs = 3/2

  Sum = 11/2 and Product = 3/2
