Answer:
The zeroes of the given polynomial are 3 & 2
Step-by-step explanation:
Let,
x²-5x+6=0
or,x²-(3+2)x+6=0
or,x²-3x-2x+6=0
or,x(x-3)-2(x-3)=0
or,(x-3)(x-2)=0
therefore,x-3=0
or,x=3
&, x-2=0
or,x=2
so, the zeroes are 3 & 2

x²-5x+6=0
x²+x-6x+6 =0
x(x+1)-6(x+1)=0
(x-6)(x+1)=0
x-6 =0
x=6
or
x+1=0
x=-1
Relationship between the zeroes
Sum=a+b= -b/a
=6-1=-(-5)/1
=5=5
Product=ab=c/a
=(6)(-1)=6
=6=6
