Question

Can someone plz help me with this math equation!

Answer 1

Answer:

x² + 2x + 9 - $\frac{7}{x+3}$

Step-by-step explanation:

Using Synthetic division

- 3 |   1    5     15   20

       ↓  - 3   - 6    - 27

     ----------------------------

       1     2      9     - 7 ← remainder r(x)

Quotient Q(x) = x² + 2x + 9

Thus

x³ + 5x² + 5x + 20 = x² + 2x +9 - $\frac{7}{x+3}$
