FInd the zeros for the following polynomial function and give the multiplicity for each zero. For each zero, state whether the graph crosses the x-axis or touches the x-axis and turns around.
8(x-5)(x+7) 3
What is the value of the zero with the smaller multiplicity?
What is the multiplicity of this zero?
What is the value of the other zero?
What is the multiplicity of this zero?
Solution
8(x-5)(x+7) 3
zeros ==> x=5 and x=-7
x=5 is having smaller multiplicity
multiplicity of x=5 is 1
other zero is x=-7
multiplicity of x=-7 is 3
multiplicity of both the zeros is odd so at these zeroes graph crosses X axis
