Solution Steps

To find the zeroes of the polynomial function and their multiplicities, identify the values of x x that make each factor zero. The exponent of each factor indicates the multiplicity of the corresponding zero.

Step 1: Identify the Factors

The given polynomial function is f(x)=(x+10)5(x4)2(x8) f(x) = (x + 10)^{5}(x - 4)^{2}(x - 8) . The factors of this polynomial are (x+10) (x + 10) , (x4) (x - 4) , and (x8) (x - 8) .

Step 2: Find the Zeroes

To find the zeroes, set each factor equal to zero:

  1. x+10=0 x + 10 = 0 gives x=10 x = -10
  2. x4=0 x - 4 = 0 gives x=4 x = 4
  3. x8=0 x - 8 = 0 gives x=8 x = 8
Step 3: Determine the Multiplicities

The multiplicity of each zero corresponds to the exponent of its factor:

  • For x=10 x = -10 , the multiplicity is 5 5 .
  • For x=4 x = 4 , the multiplicity is 2 2 .
  • For x=8 x = 8 , the multiplicity is 1 1 .

Final Answer

The zeroes and their multiplicities are:

  • x=10 x = -10 , multiplicity 5 5
  • x=4 x = 4 , multiplicity 2 2
  • x=8 x = 8 , multiplicity 1 1

Thus, the answer is x=10, multiplicity 5;x=4, multiplicity 2;x=8, multiplicity 1 \boxed{x = -10, \text{ multiplicity } 5; \, x = 4, \text{ multiplicity } 2; \, x = 8, \text{ multiplicity } 1} .
