Q. Write a polynomial of least degree with roots −8 and 9.Write your answer using the variable x and in standard form with a leading coefficient of 1.______
Factorize −8: Root −8 gives factor (x+8).
Factorize 9: Root 9 gives factor (x−9).
Multiply factors: Multiply factors: (x+8)(x−9).
Distribute: Distribute: x2−9x+8x−72.
Combine like terms: Combine like terms: x2−x−72.
