Answer:

The answer to your question is below

Step-by-step explanation:

To answer this question just clear x from the divisor.

                                 3x + 5 = 0

                                 3x + 5 - 5 = 0 - 5

                                 3x = -5

                                 3x/3 = -5/3

                                x = - 5/3                           First question

Now evaluate the function at x = - 5/3

                                p(-5/3) = 3(-5/3)⁵ + 2(-5/3)² - 5

                                p(-5/3) = 3(-3125/243) + 2(25/9) - 5

                                p(-5/3) = 3(-12.86) + 5.56 - 5

                                p(-5/3) = -38.58 + 5.56 - 5

                                p(-5/3) = -38.02                Second question
