What are all real zeros of \(p(x)=(x + 6)(x - 5)(x - 6)\)?

Let's work it out together.

Work through one checkpoint at a time. Your answer area opens after the reasoning.

Checkpoint 1

Set each linear factor equal to zero.
Checkpoint 2

The visible constant in a factor has the opposite sign from its zero.
Checkpoint 3

Keep one solution from every distinct factor.

\(x=5\)\(x=-180\)\(x=-6, 5, 6\)\(x=6, -5, -6\)
