Answer 1

Hello from MrBillDoesMath!

Answer:

See Discussion section below for details

Root 1: -2, -1

Root 2: 0, 1

Root 3: 1, 2

Discussion:

From the attached plot, the the real zeroes are approximately

-1.8, .3, 1.5

-2 < -1.8 < -1

0 < 0.3 < 1

1 < 1.5 < 2

The consecutive integers are shown in bold face

Out of curiosity, it's now 11:38am PST. Did you write the question from a public school room, a school computer lab, or are you home tutored?

Thank you,
