Solving Polynomials Extra Practice Set A

Directions: Factor each polynomial equation completely to determine its solutions, as well as the multiplicity of each solution.

1. [pic] 2. [pic]

3. [pic] 4. [pic]

5. [pic] 6. [pic]

Directions: State the solutions, as well as the multiplicity of each.

Then, write the equation in question #7 in standard form.

Also state the y-intercept of each.

7. [pic] 8. [pic]

9. [pic] 10. [pic]

Directions: In the questions that follow, some solutions to a polynomial equation are provided. Determine what additional zeros (if any) should be part of the list, given that each equation has rational coefficients. (Hint: That last part of the directions just means that the theorems we learned in class apply!)

For problems 11, 13, and 15, write the polynomial in standard form as well.

11. Solutions: -3 (M. 2) and [pic] 12. Solutions: 5i, [pic] (M. 6)

13. Solutions: [pic] [pic] 14. Solutions: [pic](M. 3), [pic] [pic]

15. Solutions: 0, -3, 10 16. Solutions: -2A (M.3)

*In this question, A is some imaginary number*
