Find the solutions of the equation Remember to use x pq wher
     Find the solutions of the equation. Remember to use x p/q where p is the constant and q is the coefficient of the first term and apply synthetic direction.  x^4 - 9x - 7 = 0  x^3 - 3x^2 - 4x + 6 = 0  x^4 + x^3 - 7x^2 - x + 6 = 0  x^3 + x^2 - 17x + 15 = 0  x^5 - 3x^3 + 4x62 - x - 2 = 0 
  
  Solution
x^4 -9x +7 =0
