2. Adding and Subtracting Polynomials (3x 2 + 2x) + (5x 2 + x) = 3x 2 + 5x 2 +2x + x = 8x 2 + 3x (3x 2 + 2x) – (5x 2 + x) = 3x 2 – 5x 2 + 2x – x = - 2x 2 + x Group like terms and simplify!

3. Simplify (3x3 + 3x2 – 4x + 5) + (x3 – 2x2 + x – 4) (3x 3 + 3x 2 – 4x + 5) + (x 3 – 2x 2 + x – 4) = 3x 3 + 3x 2 – 4x + 5 + x 3 – 2x 2 + x – 4 = 3x 3 + x 3 + 3x 2 – 2x 2 – 4x + x + 5 – 4 = 4x 3 + 1x 2 – 3x + 1

6. Which of the following could be the graph of a polynomial whose leading term is –3x 4 ?

7. ANSWER This is a degree 4 polynomial, meaning that the graph will either go up on both ends or down on both ends. Since the leading coefficient is negative, the graph will go down on both ends.

8. X- intercepts y = x 2 – x – 42 Factor→ (x + 6) (x – 7) The graph will cross the x axis at x = – 6 and x = 7 →

9. Y- intercept y = x 2 – x – 42 Substitute 0 for x to find where the graph crosses the y axis y = 0 – 0 – 42 y = 42 Graph x 2 – x – 42 →

10. y = x 2 – x – 42 ANSWER X = 7 X = - 6 Y = - 42
