• USE DRRACKET TO COMPLETE THE FOLLOWING
• Create Racket expressions to compute the values of these arithmetic expressions, and evaluate your Racket expressions.

   3 * 9 - 12 + 8 (3 * 9) - (12 + 8) 1.6 + 6 * 1/3 - -1.7 1.6 + 6 * (1/3 - -1.7) 

• Give an expression to compute the value of either of the roots of this equation:

   3x2 - 13x + 4 = 0 

  Yes, you need to use the quadratic formula!
