Full solution

Q. Write a polynomial of least degree with roots 22 and 9-9.\newlineWrite your answer using the variable xx and in standard form with a leading coefficient of 11.\newline______
  1. Factor for root 22: The factor for the root 22 is (x2)(x - 2).
  2. Factor for root 9-9: The factor for the root 9-9 is (x(9))(x - (-9)) which is (x+9)(x + 9).
  3. Multiply the factors: Now, multiply the factors to get the polynomial: (x2)(x+9)(x - 2)(x + 9).
  4. Perform the multiplication: Perform the multiplication: x(x+9)2(x+9)=x2+9x2x18x(x + 9) - 2(x + 9) = x^2 + 9x - 2x - 18.
  5. Combine like terms: Combine like terms: x2+7x18x^2 + 7x - 18.
