What does multiplicity of a zero mean?

• Look at the number of terms
• How many times the zero repeats
• Find the sum of all the coefficients
• Ratio your x and y

What are the zeros of the polynomial and state their multiplicity at each.
y = (x - 5)(x + 2)²

• x = 5 multi 1,  x = 2 multi 2
• x = -5 multi 2, x = -2 multi 1
• x = 5 multi 1, x = -2 multi 2
• x = 5 multi 2, x = -2 multi 1

• 2
• 1
• 4
• None

• The function has an Odd degree
• The function has an Even degree
• The function has 5 real zeros
• The function has a Positive coefficient

f(x)=(x+4)(x-3)(x-2)
List the zeros for this function.

• x = -4, x = 3, x = -2
• x = -4, x = 3, x = 2
• x = -4, x = -3, x = 2
• x = 4, x = -3, x = -2

Identify the zeros:

• x = -2, x = -1, x = 0
• x = -2, x = 0
• x = -1, x = 0, x = 2
• x = -2, x = 0, x = 1
