x=2" multiplicity 4", x=3" multiplicity 1"x=2 multiplicity 4,x=3 multiplicity 1

Explanation:

"zeros are the values of x that make " f(x)=0zeros are the values of x that make f(x)=0

"solve " (x-2)^4(x-3)=0solve (x2)4(x3)=0

"equate each factor to zero"equate each factor to zero

(x-2)=0rArrx=2(x2)=0x=2

rArr(x-2)^4=0rArrx=2larr" 4 times"(x2)4=0x=2 4 times

x-3=0rArrx=3larr" 1 only"x3=0x=3 1 only

rArrx=2" with multiplicity 4"x=2 with multiplicity 4

"and " x=3" with multiplicity 1"and x=3 with multiplicity 1
