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 (x−2)4(x−3)=0
"equate each factor to zero"equate each factor to zero
(x-2)=0rArrx=2(x−2)=0⇒x=2
rArr(x-2)^4=0rArrx=2larr" 4 times"⇒(x−2)4=0⇒x=2← 4 times
x-3=0rArrx=3larr" 1 only"x−3=0⇒x=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
